Have you ever paid attention to carcinogens around you? Recently, the topic of "super carcinogen Aspergillus flavus around us" has attracted attention in Weibo.

Aflatoxin is a strong carcinogen produced by Aspergillus flavus! As early as 1993, aflatoxin was classified as a class 1 carcinogen by the World Health Organization, with its toxicity 68 times that of arsenic, 10 times that of potassium cyanide, and 70 times that of dimethylnitrosamine, which is extremely destructive to liver tissue. Regular intake may increase the risk of liver cancer. [1]

In addition to aflatoxin, there are actually some "carcinogens" around us, which are likely to enter the diet and life every day.

1. Aflatoxin: moldy grain and nuts.

Among moldy foods, one kind of mildew comes from Aspergillus flavus, especially in grain. In 2007, an assessment of dietary exposure of Chinese aflatoxin published in China Journal of Food Hygiene pointed out that corn and rice were the main contribution foods to dietary exposure of Chinese aflatoxin. [2]

In addition, peanuts and peanut oil may also contain aflatoxin.

Common sources of aflatoxin

Moldy corn, rice

Moldy, especially in foods with high starch content, such as corn and rice.

Deteriorated nut

When you eat bitter nuts, you must spit them out immediately and rinse your mouth.

Broken and unclean bamboo and wood chopsticks

Chopsticks themselves will not grow Aspergillus flavus, and starch is easily hidden in unwashed chopsticks, which poses a risk of mildew.

Inferior sesame paste

Using inferior and deteriorated sesame seeds and peanuts as raw materials, aflatoxin may exist in peanuts.

Earth-pressed peanut oil

Some "earth-squeezed oil" or self-squeezed oil has no quality control, and the equipment is not easy to be thoroughly cleaned, and the residual oil stains and grain residues are easy to mildew. [3]

2. benzopyrene: food that has been roasted and fried at high temperature.

Pan Zhanhe, deputy chief physician of the Oncology Department of Zhongshan Hospital affiliated to Xiamen University, said in the Health Times article in 2017 that heterocyclic amines and polycyclic aromatic hydrocarbons may be produced in the production process by barbecue or smoking, among which the most well-known one is benzopyrene, which may be contained in many baked and smoked foods. [4]

A study published in Jinan University in 2018 found that the intake of polycyclic aromatic hydrocarbons in the barbecue process was: eating barbecue food > skin contact > lung inhalation.

This means that during barbecue, the skin absorbs more carcinogens than the lungs inhale. [5]

Common sources of benzopyrene

roast

It may be produced during barbecue or smoking.

High temperature fried food

Cooking oil will produce a lot of benzopyrene at high temperature, and the higher the oil temperature, the more it will be produced.

Cooking oil fume

The cooking fume will also carry benzopyrene, so don’t wait for the oil in the pot to smoke before putting the food. [6]

3. nitrosamines: smoked and pickled food.

Zhang Qin, vice president of Jiangsu Cancer Hospital, said in the program "Meeting a Famous Doctor" on Jiangsu City Channel in 2019 that smoked bacon food contains a lot of nitrosamines, and the incidence of some digestive system tumors, such as esophageal cancer, is related to the intake of nitrosamines in the diet. When smoked food and wine are ingested together, the harm of nitrosamines to human health will multiply. [7]

Reproduction and use of copyright pictures in the gallery may lead to copyright disputes.

Pickled products often contain more nitrite. Although nitrite itself does not cause cancer, it will combine with protein to form nitrosamines when it enters the body. In addition, some nitrosamine compounds, such as nitrosodimethylamine, will be produced in the process of dehydration of Chinese salted fish, which are carcinogenic. [8]

Common sources of nitrosamines or nitrites

Processed meat products

Nitrite is added to some processed meat products such as sausages, ham and bacon.

Overnight dish

Overnight vegetables, especially overnight green leafy vegetables, will produce nitrite, and the nutrition will be discounted.

Smoked and cured food

Pickles, salted fish, bacon, high-salt pickled and smoked foods contain nitrite. For example, the most nitrite in pickles is between two or three days and ten days after the start of pickling. [9]

4. Tobacco tar: inhaled by tobacco burning.

Smoking and second-hand tobacco smoke are classified as Class 1 carcinogens. During the burning process of cigarettes, nearly 4000 new chemicals are formed. Most of these substances are harmful to people, among which nicotine, nitric oxide and tobacco tar are the most harmful, and the latter is the chief culprit of cancer. [10]

Moreover, smoking is not only a kind of cancer that causes lung cancer, but also closely related to the occurrence of nasopharyngeal carcinoma, oral cancer, esophageal cancer and other related cancers.

5. Acetaldehyde: an intermediate product produced after drinking.

The main component of wine is ethanol, which is oxidized into acetaldehyde after entering liver cells. The latter is hepatotoxic and carcinogenic, and excessive accumulation in the body will cause serious harm to the liver. [11]

Reproduction and use of copyright pictures in the gallery may lead to copyright disputes.

Acetaldehyde related to the intake of alcoholic beverages is classified as a class 1 carcinogen. According to the statistics in the 2014 World Cancer Report, 3.5% of cancers are caused by alcohol, and one in every 30 cancer deaths is caused by alcohol. [12]

Although there are various carcinogens around us, carcinogens can cause some cancers, which refers to a possibility after long-term and excessive intake. If you only eat a little occasionally or touch it occasionally, don’t worry, it’s still safe.

In 2023, online celebrity Car will be the M7, but in 2024, online celebrity Car will become the M9. Thanks to Huawei’s belief, the M7 has achieved excellent order performance, so we will look forward to the monthly delivery limit of the M9.

According to the previous reports, the cumulative success of the M9 has exceeded the 40,000 mark, which is an excellent performance for a self-owned brand new energy vehicle with a price of over 500,000. "Far ahead" may really not be an advertisement.

So, where is the bottom spirit of M9′ s "far ahead"? The author shot M9 in the shop a few days ago. Let’s find the answer together.

In terms of appearance, the front face of Wenjie M9 adopts a relatively rounded design style, and the closed grille is more common for new energy vehicles. There are raised ribs on both sides of the front hatch cover, which has a strong sense of strength; The headlight group adopts blackening treatment, and supports projection function, which is connected by penetrating daytime running lights, effectively stretching the horizontal visual width of the front face.

The lower enclosing part adopts three-stage design, and the fenders on both sides are designed with vertically arranged guide grooves, which can improve aerodynamic performance; At the bottom, there is a large rectangular air inlet, and the interior is decorated with a banner structure, which has a strong sense of layering. The roof is also equipped with a laser radar, which means supporting high-order assisted driving functions.

In terms of side modeling, the two-color body creates a suspended roof, and the style is more fashionable; The roof is equipped with a thick luggage rack, which effectively increases the sense of strength; The waistline is through, and the chrome-plated strips around the window and the side skirt highlight the layering of the side of the car body, and at the same time make the visual effect look slender; The door handle adopts a pop-up shape, which can reduce the wind resistance; The wheel hub adopts multi-frame modeling, which gives people a more atmospheric feeling.

In terms of tail modeling, the roof is equipped with a large spoiler and high-position brake lights, and the blackened taillight group adopts a penetrating design, which effectively stretches the lateral visual width of the tail; The license plate frame area adopts concave design, which embellishes the three-dimensional sense of the rear of the car; The shape of the lower enclosing part is relatively simple, with small fog lights integrated on both sides and silver-gray rubbing plates at the bottom.

In terms of dimensions, the length, width and height of the bound M9 are 5230/1999/1800mm and the wheelbase is 3110mm, respectively, and it is positioned as a large SUV.

The interior belongs to a relatively simple design style, including a three-position multi-function steering wheel, an all-LCD instrument panel, an embedded central control panel, a co-pilot entertainment screen and an electronic fender. The overall sense of science and technology is relatively in place, and the central control panel runs HarmonyOS OS, which shows excellent performance in both functionality and fluency.

Seats adopt a six-seat layout of 2+2+2, the second row adopts two independent seats, and the central passage is relatively wide, which is convenient for the passengers in the third row to get on and off. The electric adjustment/ventilation/heating/massage of the first and second rows of seats are standard in the whole system, and the third row of seats also supports electric adjustment and heating functions.

In terms of assisted driving function, Wenjie M9 is equipped with assisted driving hardware consisting of a laser radar, 11 cameras, 12 ultrasonic radars and 3 millimeter-wave radars, which can realize high-speed NOA function, and the urban NOA function needs to be opened for a fee.

In terms of configuration, the M9 comes standard with air suspension, panoramic image, front and rear parking radar, sectional non-openable sunroof, automatic wiper, front 50W wireless charging, 25-speaker speaker and other functions.

In terms of power, the extended range version is equipped with a hybrid system consisting of a 1.5T range extender and two motors. The maximum power of the range extender is 112kW, the combined maximum power of the two motors is 365kW, the peak torque is 675N·m, and the zero acceleration time is 4.9 seconds. The battery pack capacity is 42kWh, the pure electric cruising range under CLTC condition is 225km, and the comprehensive cruising range under WLTC condition can reach 1210km.

Moreover, the extended-range version can also be equipped with a 52kWh battery pack. The pure electric cruising range of CLTC is increased to 275km, and the comprehensive cruising range of WLTC can reach 1239km.

The pure electric version is also equipped with front and rear dual motors, with a comprehensive maximum power of 390kW, a peak torque of 673N·m, and an acceleration time of 4.3 seconds. The capacity of the battery pack is 100kWh, and the pure electric cruising range of CLTC is 630km.

Concluding remarks

Through experience, the author was deeply impressed by the space and configuration of the M9. Although the appearance is full of atmosphere, the originality is not particularly high. The interior has a certain sense of science and technology, but the black edge of the instrument panel is wide, which affects the sense of grade to some extent.

At the same level, the biggest advantage of the M9 is the driver assistance function. Even though the actual effect is not clear, users trust Huawei, which is unmatched by any other brand. Perhaps this is the strength of being far ahead.

　　False death certificate

　　Screenshot of reporters chatting with merchants

　　Nowadays, handling business on behalf of the public is quite popular. Have you ever heard that a "death certificate" can also handle it? Recently, a reporter’s investigation found that you can get a death certificate without spending 200 yuan on the online platform. A merchant "intimate" said that if you need to go to court to increase your chips, you can also open a "notice of critical illness", which is more effective than a "death certificate". It is worth mentioning that during the investigation, the reporter noticed that the "death certificate" templates created by merchants are varied, and some even have incomplete basic identity information. Relevant legal persons reminded that if a merchant knows that the buyer regards it as perjury and sells it maliciously, it is suspected of violating the law.

　　shock

　　You can open a "death certificate" without going to 200 yuan.

　　Merchant: There are formal channels in the hospital.

　　On the morning of November 22nd, the reporter searched for the word "critically ill" on Taobao platform, and some agency businesses popped up, with the key words marked as providing sick leave and other services. When private messages are asked, merchants will often ask consultants to add their WeChat. The reporter tweeted and added WeChat of three merchants.

　　The first merchant said that he could issue a death certificate, the price of which was 130 yuan, and he only needed to tell his name, ID number, address and time of death. Another businessman said that he can issue death certificates from hospitals all over the country. "160 yuan from a regular top three hospital needs his name, ID number, time of death and why he died." The merchant said that he has formal channels in the hospital. The third merchant said that his death certificate was sold in 150 yuan, which was also true.

　　The reporter noticed that the templates of death certificates provided by the three merchants are different. Some only indicate the patient’s name, age, hospitalization number, cause of death and time of death, while others are very comprehensive, including identity number, actual age, specific place of death (hospital ward, emergency room, on the way to the hospital), the cause of death, and the highest diagnostic basis of the disease.

　　More shocked

　　You can also open a notice of critical illness

　　Merchants: You can increase your "chips" when defending your rights.

　　During the conversation, a merchant said that his own death certificate can be used to open a hospital or a police station, and the price of the death certificate of the police station is relatively high. Immediately, he said that it is necessary to know the purpose of the death certificate. If the death certificate is used for criminal disputes through legal channels, it will not be issued. "That risk is too great, and you are also dangerous. The death certificate of the hospital can be opened here." "

　　Later, the merchant said that if a person has not died and needs to go to court or defend his rights, he can issue a corresponding notice of critical illness to the hospital. "If you take it, you will raise your chips. If you really die, you will not pay so much, and the notice of critical illness will pay more." In response to the question raised by the reporter of the New Yellow River whether it is reliable and whether the hospital will verify it, the other party said that "people lying in bed are also critically ill. If you die, it is unrealistic. After all, people are not really dead. The critically ill notice is already very serious, and it will definitely increase the chips. I can also open an injury appraisal here, and I can give you a serious one. "

　　The reporter found in the China Judgment Document Network that some civil disputes really revolved around the falsification of injury identification, and some litigants complained that the injured did not touch some parts, but their injury identification documents showed different results.

　　Distinguish truth from falsehood

　　Medical practitioners: part of the proof is "fake at a glance"

　　Is the "fake death" certificate provided by the above-mentioned merchants reliable? The reporter consulted two staff members of the top three hospitals. The other party said that some death certificates did not even indicate the information such as the ID number of the deceased, which was a "one-look leave".

　　Speak the law

　　Lawyer:

　　Handling false death certificates

　　It is a crime

　　Search found that in recent years, there are not a few oolong mistakes caused by forging death certificates. In 2020, a man in Jiangsu was released on bail for defrauding 1.9 million yuan, in an attempt to evade the trial by giving himself a fake death certificate, cremation certificate and account cancellation certificate. In the end, the man was added to the crime of forging official documents and seals of state organs.

　　"Formal judicial authentication documents often come from judicial authentication centers and need to check their qualifications. Casual injury identification, death certificate, etc., if used for dispute handling, the court also needs to examine its authenticity. " Lawyer Yuan Qian of Shandong Zhengtang Law Firm said that such acts as men obtaining false death certificates to get rid of crimes are very bad in nature and have been criminal acts.

　　The reporter learned that according to the Criminal Law of People’s Republic of China (PRC), forging, altering, buying or selling or stealing, robbing or destroying official documents, certificates and seals of state organs are sentenced to fixed-term imprisonment of not more than three years, criminal detention, public surveillance or deprivation of political rights; If the circumstances are serious, he shall be sentenced to fixed-term imprisonment of not less than 3 years but not more than 10 years. Whoever forges the seal of a company, enterprise, institution or people’s organization shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention, public surveillance or deprivation of political rights.

　　According to the new yellow river client

　　Spend 130 yuan to "fake death"

　　How can the platform be really blind?

　　Journalists can find these fake shops through keyword search and other methods. If the platform with more information and data is really managed, it is impossible to manage it.

　　Critical notice and death certificate are extremely serious medical documents, which are related to people’s life and death. However, such documents are actually sold on the Internet at will, and you only need to spend more than 100 yuan to provide your ID number, address and time of death, and you can choose the death certificates of hospitals all over the country. From the convenience of purchase and the low cost of counterfeiting, we can see how mature the "grey production chain" behind the proof has reached.

　　The fraud of critical notice and death certificate is obvious. In 2020, a man in Jiangsu was released on bail for defrauding 1.9 million yuan, in an attempt to evade the trial by giving himself a fake death certificate, cremation certificate and account cancellation certificate. In addition, news such as helping yourself to defend your rights by issuing a certificate, which is used to defraud insurance, also appears from time to time. It is conceivable that false proof of "grey property" not only undermines social integrity, but also inevitably encourages a large number of illegal and criminal acts, bringing unpredictable risks to society.

　　Similar to proving counterfeiting, both buyers and sellers have violated the law. Merchants who forge such certificates for a certain amount or times, or cause serious harmful consequences, will be suspected of forging, altering, buying and selling official documents, certificates and seals of state organs. The Law on Public Security Administration Punishment also has corresponding penalties for "buying, selling or using forged or altered official documents, certificates and supporting documents of state organs, people’s organizations, enterprises, institutions or other organizations". However, why is the underground chain behind this still rampant?

　　Among them, the indulgence of related platforms is probably a key factor. In fact, it is nothing new to falsify critically ill notices and death certificates. Over the years, there have been constant media reports. However, often, as soon as there is media intervention, the relevant platforms will pay attention to it. For example, last year, a man in Jiangsu bought a fake death certificate and tried to escape the trial, and the relevant online stores were cleaned up. It can wait until the news is over, and the daily management of the platform becomes lax, which proves that "gray production" will make a comeback.

　　Admittedly, the transaction of forged certificates has certain concealment. For example, according to the investigation of reporters, some shops are drained through the online platform, and then negotiate and trade through WeChat, which will indeed bring certain difficulties to the supervision of the platform. However, if you make full use of big data, it is not difficult to identify these illegal shops. Journalists can find these fake shops through keyword search and other methods. If the platform with more information and data is really managed, it is impossible to manage it.

　　Of course, for the supervision of similar forged certification transactions, we can’t just hope for the platform’s consciousness. As the relevant regulatory authorities, they also have the responsibility to supervise and compact the main responsibility of each platform. For the network platform that indulges and proves "gray production", it is not just self-examination and correction, but should be punished according to law. In this way, we can force the platform to "keep the soil responsible" and try our best to cut off the trading chain that proves "gray production".

　　Beijing, 24 Nov (reporter Fan Weichen from Zhongqing Daily, Zhongqing.com) Today, Beijing Education Examinations Institute announced the Scoring Standard for Physical Education and Health Assessment of Compulsory Education in Beijing (hereinafter referred to as "Scoring Standard"), which was put into use in the senior high school entrance examination in 2024.

　　In December, 2021, Beijing Municipal Education Commission issued "Beijing Compulsory Education Physical Education and Health Assessment Scheme", which not only increased the process assessment, but also greatly adjusted the content of on-the-spot examination, further expanded the number of items, and adopted the method of classifying and restricting the selection. It was divided into four categories and set up 22 examination contents, of which the first category (quality item 1) middle-distance running events (1000m for boys and 800m for girls) were required.

　　According to reports, compared with the original on-site examination items of the senior high school entrance examination for physical education, on the one hand, Beijing has scientifically adjusted the original item standards, including five items: 1000 meters for boys, 800 meters for girls, pull-ups, sit-ups and solid balls, among which four items, 1000 meters for boys, 800 meters for girls, pull-ups and sit-ups, are also the National Physical Health Standards for Students (revised in 2014) On the basis of comprehensive analysis of the data of physical education senior high school entrance examination, sampling test and unified test since 2017, according to the national students’ physical health standards, it is adjusted according to the principle of "reaching good is full score". On the other hand, the standards for newly added items are formulated scientifically, and the 17 newly added items are also formulated in accordance with the principle of "reaching good marks means full marks", with reference to the National Physical Training Standards, sports-related standards for senior high school entrance examinations in other provinces and cities, empirical data analysis and expert argumentation opinions. The new project is not more difficult than the original project.

　　"The purpose of physical education entering the senior high school entrance examination is not to assign children three or six grades through the examination, but to give physical education ‘ A place ’ Let parents realize the importance of good health and physical exercise. " Zhang Shuang, an expert who participated in the demonstration of scoring criteria and dean and professor of the School of Education of Capital Normal University, said.

　　According to the Beijing Education Examinations Institute, considering the characteristics of many examination items, many candidates’ choice combinations and different requirements for venues, the examination room will be arranged according to the candidates’ choice combinations and the characteristics of each item. In terms of examination organization, each district will organize the implementation according to the principle of "unified examination time, unified examination items, unified examination rules, unified grading standards, unified venue equipment settings and equipment standards". Each test center is equipped with relevant areas such as candidate assembly area, preparation area, examination area and rescue area, reasonably arrange the examination venues and equipment for each project, and scientifically plan the examination path. During the examination, candidates will be organized and guided by special personnel according to the project and grouping situation to ensure that candidates complete the examination according to the optimization process.

　　On August 20th, the 2019 World Robotics Congress kicked off in Yizhuang, Beijing. More than 180 well-known enterprises from the global robotics field made amazing appearances with more than 700 cutting-edge products. It was not only an exposition where robots showed their talents and competed with each other, but also an exploration and practice of presenting researchers with "animals" (bionic robots), "people" (commercial robots) and "tools" (intelligent manufacturing equipment) as the innovation direction, so that

　　Big birds, jellyfish, sharks … …

　　Bionic robots are particularly dazzling.

　　Nature and science and technology seem to be two very different disciplines, but in fact they are inextricably linked. At this World Robotics Congress, "bionic robots" that imitate biology and engage in biological characteristics are particularly evident.

　　“3、2、1!” At the moment when the silver-white bird model suddenly flickered its wings and flew vigorously into the air, the audience gave out bursts of exclamation. I saw that it sometimes rotates and sometimes vibrates its arms. After dozens of seconds, it can fly back to the "master’s" arms accurately.

　　According to the relevant person in charge of festo, this intelligent flying bird was designed as a high-performance and ultra-light flying model by the R&D personnel on the basis of successfully analyzing the flight mechanism of birds. Its aerodynamic characteristics are excellent and extremely dexterous. Its wings can not only flap up and down, but also be driven to a specific angle by an active articulated torsion drive unit, and the electronic system integrated on it can accurately and efficiently control its torsion according to the wing position.

　　ROBK-SHARK intelligent bionic shark unmanned submersible developed by Boya Gongdao is also an industrial underwater fish robot platform. According to reports, it uses a three-joint bionic tail fin as the only power source, and is equipped with a 110 wide-angle and 16 times optical zoom starlight camera. The shell adopts membrane vibration sound absorption structure, which can realize underwater low noise work, thus greatly improving the concealment of the equipment.

　　Smart arms, flexible lower limbs, and brain-brain switching … …

　　Humanoid commercial robots are amazing.

　　In the development of robots, imitating human beings has always been one of the main directions. There have been many amazing achievements in the field of humanoid commercial robots.

　　German Agile Robots (Beijing Siling Robot) and Kinifinity jointly developed the wearable motion capture device (glove+coat), which can control the operation of the mechanical arm and dexterous hand freely and remotely, such as steadily grabbing the mineral water bottle and continuously pouring water into the glass. Li Yang, marketing department of Beijing Siling Robot, said that this kind of motion capture remote control equipment has been applied to related operations in space to some extent.

　　In the just-released Guoman Ne Zha, Yi Er’s equipment is mixed with Tian Ling and hot wheels, which is deeply rooted in people’s hearts. Nowadays, the best friend "Little Nezha" (U06), which is similar to Yier’s actions in the field of robotics, makes its debut, and its freely coordinated movement of lower limbs is amazing. According to Liu Xuenan, CEO of Kangli Youlan, it has the ability to intelligently adapt to various complex environments through the combination of lower limb movements with wheeled gait and efficient combination of fast and slow doubles.

　　Chuangchuang, an intelligent business service robot, seems to be able to "see through" children’s temper. According to the relevant person in charge of Chuangze, its biggest feature is to take the lead in completely opening the "brain" and "cerebellum" of robots to users, so that you can quickly learn professional knowledge in various industries and become an "expert".

　　Intelligent manufacturing, warehousing and logistics, diving equipment & HELIP; …

　　Tool robot catches people’s eyes

　　Walking into the industrial robot exhibition area, the most eye-catching thing is that a complete blue intelligent robot arc welding production line is placed in the booth of Shougang in An Chuan. According to Cao Li, deputy general manager of the company, this system can be used to assemble automobile parts intelligently, accurately and efficiently.

　　The L4 logistics unmanned vehicle of Jingdong Logistics can achieve high-precision positioning at the lane level, accurately identify pedestrians, traffic signs and avoid obstacles through the deep integration of laser and vision and the use of high-precision maps. There is also its self-developed Chinese pallet access system, which mainly includes ground wolf AGV, six-axis mechanical arm and vision system, unmanned stacking forklift, four-way shuttle car and three-dimensional shelves.

　　Harbin Institute of Technology Robot Group brought a wearable underwater power backpack developed by one of its technology companies, which is novel and unique. This underwater swimming aid, which can be switched between various sports modes, has a backpack weighing 6.8kg (including battery) and a battery life of 50 minutes. Using the power generated by the electric propeller, divers can complete some difficult movements on the surface and underwater.

Another institutional innovation of patent transformation and application has been comprehensively promoted!

On June 1, 2021, the newly revised patent law was implemented, and the patent open licensing system was added. This system is conducive to the realization of "one-to-many" patent licensing, reducing institutional transaction costs, improving the efficiency of patent transformation, and opening up the "last mile" of the transformation of scientific and technological achievements into new quality productivity. With the newly revised Detailed Rules for the Implementation of the Patent Law of People’s Republic of China (PRC) officially implemented on January 20th, 2024, the patent open licensing system has been fully implemented. The patentee voluntarily submits a patent opening license statement, and the patent license fee is clearly marked, which is "widely announced" to the whole society by the patent administrative department of the State Council. Any unit or individual can obtain an implementation license by notifying the patentee in writing and paying according to the marked price, and all licensees are treated equally.

Recently, China National Intellectual Property Administration issued a notice on comprehensively promoting the implementation of the patent open licensing system (hereinafter referred to as the notice) and the Measures for the Mediation of Disputes in the Implementation of Patent Open Licensing (for Trial Implementation) (hereinafter referred to as the "Working Measures") and other documents to standardize related work and further promote the implementation of the patent open licensing system.

Open license to build a patent docking bridge

"In just half a year, this patent has created an economic value of nearly 10 million yuan for us!" Hu Chenguang, general manager of Mingji Erffa Intelligent Industrial Technology (Dalian) Co., Ltd. told the reporter. This small and medium-sized enterprise located in Dalian, Liaoning Province, is committed to developing industrial robot automation technology and equipment. At the end of last year, Hu Chenguang found in the local trading center that Dalian University’s open license patent "an improved Smith predictive control method based on CRNs" met the technical requirements of enterprises, and thus cooperated with the research team of associate professor Lu Hui of Dalian University in the automatic control of biochemical systems. This patent was applied to the company’s industrial robots and automatic cleaning equipment, which greatly improved the system performance of the equipment.

"I didn’t expect to reach a cooperation so smoothly this time. We are very eager to achieve technological breakthroughs in our products. In the past, companies looking for patents faced the problems of dislocation of demand and research and unequal information, so it was difficult to find patent acquisition channels. In the patent open licensing work, publicly displaying the patents with conversion intention in colleges and universities allows us to find more good patents. " Hu Chenguang said.

This is a vivid practice for Dalian University to gain market value through patent opening license.

As early as May, 2022, China National Intellectual Property Administration launched the pilot project of patent conversion and open license. By the end of 2023, more than 3,200 patentees in 22 pilot provinces of patent opening license had participated in the pilot project, and more than 59,000 patents were matched and pushed to more than 110,000 small and medium-sized enterprises, and more than 17,000 patents were granted. Since January 20th this year, the patent opening license statement put forward by the patentee has been announced to the public through the patent bulletin after passing the examination in China National Intellectual Property Administration.

At present, 90 patents of Dalian University have been approved for announcement. "In 2022, when China launched the pilot project of patent opening license, the school actively explored this innovative measure. The patent open license allows the school to further establish a cooperative relationship with enterprises in Industry-University-Research, which more effectively promotes the wide application of technology. " Chen Huiyuan, a researcher at the Science and Technology Department of Dalian University, said that at present, more than 20 enterprises have applied to renew their contracts and explore further cooperation after transforming and applying the school open license patents.

In the statement of patent opening license issued by China National Intellectual Property Administration, many enterprises are actively carrying out patent opening license besides universities and scientific research institutions. Jingxin Communication Technology (Guangzhou) Co., Ltd. (hereinafter referred to as Jingxin Communication) is one of them.

"The company proposed a key technical solution for high-performance low-carbon life antenna, which realized the double improvement of network performance and green energy saving, and laid a technical foundation for the realization of full-band high-performance low-carbon life antenna. In order to make green antenna technology more widely and deeply applied and promoted in the industry, we screened two core technology patents for open licensing, and combined with patent technology, market, law and other factors, conducted multi-dimensional patent valuation and determined the patent open licensing fee. " Li Xuefeng, senior vice president of Jingxin Communication, told the reporter.

At present, these two patents have successfully obtained a total of 2.5 million yuan in license fees. Li Xuefeng said that the rapid application of the open license patent not only showed the core competitiveness of the company’s independent intellectual property rights, but also helped to enhance its popularity and brand value, further promoting the prosperity and win-win situation of the industry ecology.

Supporting measures to promote the efficient operation of the system

The notice issued this time and the "Working Measures" have standardized a number of tasks in the implementation of the patent open licensing system.

According to the notice, the patent open license statement will be announced to the public through the patent bulletin after passing the examination by China National Intellectual Property Administration, and the public can inquire about the announcement information such as the patent open license statement and the registration of the license through the China Patent Publication Announcement System (http://epub.cnipa.gov.cn/). Patent open license announcement data is fully open to the public through the public service system of intellectual property data resources, which is convenient for all parties to inquire, retrieve and obtain. For the patent opening license reached, the intellectual property offices of all provinces (municipalities directly under the Central Government and autonomous regions) shall supervise and guide the patentee or licensee to file with China National Intellectual Property Administration in a timely manner in accordance with relevant regulations.

With regard to the estimation of licensing fees for patent opening, which is of concern to the industry, the notice is clear. According to the provisions of the Patent Examination Guide, the licensing fees paid at a fixed fee standard are generally not higher than 20 million yuan; Paid by royalty, generally not higher than 20% of net sales or 40% of profit. If the license fee is higher than the above standard, the patentee shall be guided to license by means of ordinary license.

At the same time, the notice requires that the intellectual property offices of all provinces (municipalities directly under the Central Government and autonomous regions) should strengthen the interpretation of the national standards of the Guidelines for Patent Evaluation and the Guidelines for Estimating the Use of Open Licenses (for Trial Implementation), and guide the patentees to uphold the concept of fairness, rationality, mutual benefit and practicality, accurately grasp the "one-to-many" characteristics of open licenses and the characteristics of small amount, inclusiveness and convenience, and reasonably estimate the license fees.

Focusing on possible intellectual property disputes, the Working Measures clarify the acceptance conditions of the application for mediation of disputes in the implementation of patent open license, the documents and materials that the parties should submit, the conditions for making an acceptance decision, the circumstances of non-acceptance and the acceptance registration, etc., so as to timely resolve the disputes arising in the implementation of patent open license.

"The patent open license system aims to promote the patent transformation and application. Its core system function is to solve the problem of asymmetric supply and demand of patent license, which can effectively promote the disclosure of transaction information and reduce the transaction cost of patent license, thus promoting the patent transformation and implementation." Ma Yide, dean and professor of the School of Intellectual Property, University of Chinese Academy of Sciences, suggested that for the innovation subject, whether the patent license is achieved depends on the docking of market supply and demand. We should fully consider the patent quality and market demand, and open the license for high-value patents that meet the market demand. For the enterprises that accept the open license, after the open license is reached, they should actively file with China National Intellectual Property Administration to maintain the priority effect of obtaining the license, so as to avoid the right holder’s punishment of the patent during the open license period, which will affect the interests of the implementers. At the same time, the declaration of open license can also enable the public to make reasonable investment planning by understanding the implementation of the open license of a specific patent, so as to avoid disorderly competition or excessive investment caused by the large number of licensees of the same patent.(Author CoCo WU)

　　Our reporter Li Muming

　　Compared with the "snarling" smog, ozone is much more "low-key" and quietly "hidden" in the clear sky of Wan Li, but it has become the culprit of atmospheric environmental pollution in many cities since it was included in the monitoring indicators in summer in recent years. Statistics of air quality in 74 cities across the country show that among all the days exceeding the standard in June 2015, the days with ozone as the primary pollutant were the most, exceeding the days with PM2.5 as the primary pollutant. In response, on July 23, Guangdong Province announced the air quality of urban environment in the second quarter of 2015, and ozone became the most common primary pollutant; According to media reports, ozone replaced PM2.5 as the primary air pollutant in nearly half of the pollution days in Beijing, Tianjin and Hebei from June to August.

　　Why is PM2.5, which is well known and concerned by the public, "surpassed" by ozone? What harm does ozone do to human body?　　　　　　　　　　　　　　　　

　　1. "Low-key" ozone is more terrible than PM2.5

　　Experts believe that the invisible pollution of ozone should not be underestimated, and comprehensive measures should be taken to prevent it, just like smog.

　　"In fact, ozone pollution has become a new environmental protection issue that plagues the whole country." Wang Yuesi, a researcher at the Institute of Atmospheric Physics, Chinese Academy of Sciences, said. At present, from a national perspective, there is one peak of ozone pollution in the north, while there are two peaks in the south every year. Even Xinjiang, Tibet and other regions are facing ozone pollution problems.

　　Compared with physical pollution such as black and smelly water pollution, yellow and black smoke pollution with pungent smell, and smog pollution mixed with fine particles, the public and even the environmental protection department have always taken colorless and odorless ozone pollution lightly.

　　But ozone is actually more terrible than PM2.5

　　Ozone can react with almost any biological tissue and is very destructive to the respiratory tract. According to the Canadian Center for Occupational Health and Safety (CCOHS), "ozone can irritate and damage the nasal mucosa and respiratory tract, which can cause chest tightness, cough, sore throat, asthma, aggravation of upper respiratory tract diseases, and may also lead to weakened lung function, emphysema and lung tissue damage, and these injuries are often irreparable." Therefore, for people with asthma, emphysema and chronic bronchitis, as long as they are exposed to low-concentration ozone, they may have obvious harm.

　　Similarly, ozone can also irritate the eyes, reducing visual sensitivity and vision. It will also destroy vitamin E in the skin and make the skin wrinkle and black spots. When the ozone concentration is above 200 μ g/m3, it will damage the central nervous system, causing headaches, chest pains and decreased thinking ability.

　　In addition, ozone will hinder the function of blood oxygen transmission, resulting in tissue hypoxia; Impairment of thyroid function and calcification of bones. Professor Paul Wentworth of Scripps Institute of Applied Science in the United States has done research and found that ozone can destroy the immune function of human body, induce chromosome aberration of lymphocytes, damage the activity of some enzymes and produce hemolytic reaction.

　　Even for plants, ozone is not a welcome good thing. Biologists from the University of Valencia, Spain, published a paper in 2006, suggesting that ozone will reduce the concentration of chlorophyll, carotenoids and carbohydrates in plants, which will affect photosynthesis and thus reduce the yield of crops.

　　2. The most dangerous population: pregnant women and children.

　　Because the proportion of ozone is about 1.66 times that of air, it often gathers in the lower space, so small children are the most direct victims.

　　Scientists in Southern California have conducted a five-year follow-up survey on 3,535 children aged 10 to 16, and found that in areas with high ozone concentration (the annual average concentration is between 112 and 138μg/m3), the incidence of asthma in children who often play three or four kinds of sports is twice as high as that in children who do not exercise. Especially, children with low birth weight or premature infants are more likely to be affected by ozone.

　　If the pregnant woman is exposed to ozone during pregnancy, the baby born may have congenital blepharoptosis (also called congenital microphthalmia, which is usually caused by the unsatisfactory development of fetal eyeball during the third month of pregnancy).

　　Another study called AHSMOG is aimed at adults. This study, which began in 1977, followed up 3091 adult non-smoking Americans aged 27-87 for 15 years. The results showed that men who were often exposed to ozone showed symptoms of lung damage. In addition, the incidence and mortality of lung cancer were closely related to long-term exposure to ozone.

　　3. The most dangerous place: the aircraft cabin.

　　Since ozone is so harmful, when is its high incidence?

　　According to the "State Key Laboratory of Organic Geochemistry" of Chinese Academy of Sciences, the timeliness and seasonality of ozone are obvious. The ozone concentration is very low in the early morning. After 8 o’clock, with more and more waste gas forming ozone and longer sunshine time, the ozone concentration gradually increases, reaching the peak between 14 o’clock and 16 o’clock, then slowly decreasing, and finally returning to the lowest state after 8 o’clock in the evening. During the year, the peak of ozone concentration is concentrated in summer. During this period, the formation of ozone can be described as "the right time, the right place and the right people": strong sunshine, less clouds and weak wind. This is the reason why people have throat, eyes and nose discomfort when they play when it seems sunny.

　　In terms of regional distribution, the ozone concentration in urban suburbs and scenic spots is often higher than that in the city center, especially when the suburbs are in the downwind of the city. In this regard, the experts’ explanation is that ozone is particularly lively and will continue to react with other pollutants after it is formed. Therefore, the increasing pollution discharge in the city center will temporarily "eat" ozone, turn it into other pollutants, and then drift to the suburbs with the wind and change it back into ozone. That is to say, even if the ozone concentration measured in the urban area is better than that in the suburbs, there is nothing to be proud of, which mostly shows that there are too many other pollutants in the urban area, which temporarily mutates the ozone.

　　The urban area is also polluted, and the scenic spots in the suburbs can’t escape. Where else can we stay? The advice of the World Health Organization (WHO) is: "Try not to expect to be outdoors when the ozone is high."

　　According to the test of the Environmental Protection Agency (EPA), the ozone concentration indoors is generally 50% lower than that outdoors. If the room is well sealed and air conditioning system is adopted, the ozone concentration will be even lower. However, sparks from motor operation, xerography and the working process of TV set will turn some oxygen in the air into ozone. Therefore, mechanical and electrical rooms, electrostatic copier rooms, computer rooms, etc. are all places with high ozone incidence, but attention should be paid to ventilation.

　　There is also an "indoor" where ozone is concentrated-the airplane cockpit. The ozone in the engine room mainly comes from the atmospheric environment, and the ozone layer is mainly distributed in the atmosphere at an altitude of 10 km to 50 km, while the flying height of civil aircraft is generally 7 km to 12 km.

　　Modern large passenger planes are equipped with ozone removal systems, but it is still impossible to kill them all. The Canadian side has tested that when the Boeing plane flies at an altitude of 11,895 meters, the external ozone concentration is 3.57mg/m3, and the ozone concentration in the aircraft cabin is 0.29mg/m3. According to a survey funded by the Federal Aviation Administration (FAA), the ozone content in the cockpit of Boeing 747, 727, 737, DC10 and DC9 is relatively high, and the ozone content in the cockpit of long-range aircraft is higher than that of short-haul aircraft. The leader of this survey is William nazarov, an environmental engineer at the University of California. He believes that the solution to the ozone problem in the cockpit is simple, that is, adding an ozone converter to the aircraft. "Unfortunately, not all airlines have this awareness, especially for old and small aircraft. Airlines are more concerned about flight safety."

　　4. How does ozone pollution come about?

　　Due to the increasingly obvious harm of ozone, the international safety standards for ozone are becoming stricter and stricter. The "maximum 8-hour daily average" of ozone stipulated by the European Union has dropped to 60nmol/mol (about 120 μ g/m3) in 2010, and the average number of days in a year cannot exceed this standard for more than 25 days. China’s newly revised Ambient Air Quality Standard in 2012 also added the ozone control standard: the daily maximum 8-hour average value is 100 μ g/m3 for Grade I and 160 μ g/m3 for Grade II.

　　However, it is impossible to assign a general safety value to everyone. "Personal physique, exercise frequency, time spent outdoors, and other pollutants in the air will all affect the harm degree of ozone, which is the headache for the research department." Professor Jerry Martin from the School of Public Health of the University of California explained, "More and more studies have proved that even if the ozone concentration is low, if the human body is exposed for a long time (6-8 hours), the harm will be equally serious. Moreover, ozone will also work in conjunction with other pollutants. For example, ozone will enhance the harm of PM (inhalable particulate matter) to the human body, and PM will also enhance the harm of ozone. "　　　　

　　"It is better to call it photochemical pollution than ozone pollution. Primary pollutants, such as volatile organic pollutants (VOCs) and nitrogen oxides (NOx), which are discharged into the atmosphere by pollution sources such as automobiles and factories, absorb the energy of sunlight under strong ultraviolet irradiation, so that the original chemical chain is destroyed and photochemical reactions occur, resulting in secondary pollutants such as ozone and peroxyacetyl nitrate (PAN). The mixture of primary pollutants and secondary pollutants involved in the photochemical reaction process is called photochemical smog. Ozone is the main component of photochemical smog. When people monitor these pollutants, ozone concentration is also the most important indicator. " China Meteorological Bureau introduced this in its official blog.

　　5. The governance is difficult, and the top-level design needs to be strengthened.

　　Ozone pollution is an international topic. After decades of treatment in Los Angeles, the situation has greatly improved, but ozone still exceeds the standard for several days every year. Different from the single ozone pollution in the United States, ozone and PM2.5 are intertwined and interact in China, and it is just starting, so it is more difficult to control.

　　At the same time, it is not easy to monitor ozone. Wen Yanping, director of Taiyuan Environmental Monitoring Center, said that volatile organic compounds are one of the important precursors of ozone. However, the monitoring work has just started, and its sources and emissions are still in the stage of research and analysis, investigation and research, and its control is also in a state of no standard in the country, immature technology and conscious enterprise.

　　In addition, ozone monitoring does not have standard gas like sulfur dioxide, so it can easily check the error of monitoring equipment, and it can only take the equipment to Shanghai and other cities to "test the equipment with equipment", which will affect the monitoring of ozone.

　　Comprehensive control measures of ozone pollution need further research and exploration. Wang Yuesi said that the formation mechanism of ozone is a nonlinear process. Precursors, such as volatile organic compounds (VOCs) and nitrogen oxides (NOx), which can promote ozone generation, must be treated first to control ozone. However, the atmospheric ozone concentration will be effectively reduced only if it is reduced in proportion, which is not easy to handle at present. If only one kind is reduced, it is possible that the ozone concentration will increase instead.

　　The Air Pollution Prevention Action Plan issued by the State Council in 2013 clearly stated that it is necessary to "strengthen the research on the formation mechanism, source analysis, migration law, monitoring and early warning of haze and ozone, and provide scientific support for pollution control". Experts in the industry believe that governments at all levels must attach great importance to ozone pollution, a new environmental protection topic, and should take comprehensive control measures on the basis of strengthening basic research and top-level design.

　　Environmental experts say that ozone prevention and control first needs top-level design. Chai Fahe, vice president of china environmental science Research Institute, and others believe that ozone precursors should be included in the national emission reduction targets, and a total control plan for volatile organic compounds and nitrogen oxides should be formulated. Chai Fahe said that ozone precursor is also a kind of precursor of PM2.5 secondary particles. Ozone and PM2.5 treatment should be combined, and comprehensive consideration should not be made. In addition, since ozone pollution is a photochemical pollution, the pollution is aggravated when the temperature is high, so ozone should also be considered when considering global warming.

　　Wang Yuesi also suggested the implementation of comprehensive regional management. Ozone precursors are highly mobile substances, and nitrogen oxides produced in one area may not be felt by local people, but float to other places to form ozone. The effect of ozone control in a single city will not be too obvious, and regional prevention and control mechanisms should be established in areas with serious ozone pollution such as five provinces in North China, Yangtze River Delta and Pearl River Delta.

　　Chai Fahe said that the proportion of ozone precursors is different in different places, and even in the same city, the proportion between urban and suburban areas is different. All localities should make clear the ozone formation mechanism in different places, and find out the specific proportion of ozone precursors and the location of emission sources through monitoring, so as to "prescribe the right medicine". And this work needs the cooperation of environmental protection departments and scientific research institutions.

　　Experts also believe that from the technical level, the focus of ozone precursor control should be on "vehicles, oil, roads and factories": improving automobile exhaust emission standards, improving automobile exhaust devices and reducing emissions; Improve fuel quality; At the same time, gradually switch buses and taxis to gas; Control traffic congestion; Eliminate backward production capacity and control nitrogen oxides and volatiles emitted by coal-fired power plants, cement, coatings, ink printing plants and other enterprises.

　　Top-level design doesn’t mean that it has nothing to do with the general public. Do a little thing that everyone can do to protect the health of themselves and their families. The development of human society will always rise in a spiral curve. As long as we don’t escape and give up, there are always more ways than problems.

　　◆ Small information

　　Ozone is just one word short of oxygen that sustains human life, and one more o, but it is the difference between graphite and diamond. Yes, these two groups of things, which are as different as heaven and earth, are allotropes, that is, simple substances made of the same single chemical element but with different properties.

　　Because there is one more oxygen atom than oxygen, ozone is more oxidizing than oxygen. What is oxidation? The cut apple will turn brown after a while because it is oxidized by oxygen in the air; The girls’ tender faces are getting older day by day, which is the result of her body oxidation. Ozone is more oxidizing than oxygen. To what extent? Have you smelled chlorine in tap water and swimming pool? That’s for disinfection. It needs to be disinfected with ozone, which is stronger than chlorine. Therefore, the upper floors of household disinfection cabinets are disinfected by ozone.

　　Walking on the busy streets, we sometimes feel that the air is light brown with a pungent smell, which is commonly called photochemical smog, and ozone is one of the most important components in it. There are a lot of nitrogen oxides and volatile organic compounds in automobile exhaust and factory smoke, which combine with oxygen in the air and form ozone under the catalysis of sunlight radiation and temperature.　

　　It has been half a month since the normalization of nucleic acid screening in various places. As the weather turns hot, the work of nucleic acid sampling and sample transportation becomes more difficult. Experts said that although the working environment is even worse, especially for some outdoor sampling points, the sample collection, storage and transshipment work should still be carried out in accordance with the specifications and should not be slack.

　　Battery car transfer sample

　　June 15th is the first hot day since Shanghai entered Mei, with the temperature climbing to 36 degrees and the outdoor ground temperature even higher. The first financial reporter saw in an open-air nucleic acid detection point in Shanghai that the temporary tent could not stop the scorching sun, and the sampling personnel wore protective clothing, and their faces were sweating, while there were no electric fans or cooled ice cubes outdoors. Also exposed to the scorching sun are tubes of nucleic acid reagent samples being collected.

　　The sampling time at this sampling point is from 1: 00 to 4: 00 in the afternoon. After the sampling stopped at 4: 00, the staff put the last batch of samples into a suitcase-sized small refrigerator, which was close to 4: 30. A courier arrived at the testing point by car battery car, ready to take them away.

　　I saw that the picker opened the refrigerator and hastily stuffed nearly 20 tubes of nucleic acid reagents in sealed bags into black shoulder bags, while the battery car was filled with yellow medical waste bags collected from multiple inspection points.

　　Now he will carry the samples and medical wastes to a nearby "transfer station", and then these uniformly collected samples will be transferred to the designated testing laboratory by special vehicles. He claimed that this was the sixth time he had transshipped samples today, three times in the morning and three times in the afternoon, thus ending the six-hour working day agreed in the contract.

　　According to the transshipman, the point where he collects samples every day is not completely fixed, and sometimes an extra sampling point is added temporarily, which leads to the delay of his arrival at the next point, so the actual working time is more than 6 hours.

　　A sampler of normalized nucleic acid kiosks told the First Financial Reporter that in principle, a batch of samples will be transported away every hour, but in practice, the time is not so fixed, mainly depending on whether there are enough people to transport them. Their main tool is a battery car, which transports the reagents collected from several nearby testing points to the assembly point and then sends them to the testing laboratory by special car.

　　However, for the above process, an infectious disease expert with rich field sampling experience said that this sample processing method is worrying, and the sample storage and transshipment are very inconsistent with the basic norms.

　　"We who do infectious diseases know that the most important thing is that all operations must be carried out in strict accordance with norms and standards. The storage temperature and transfer time of nucleic acid samples have strict standardized processes, which is definitely not convenient." The above experts told the First Financial Reporter.

　　The guide has clearly stipulated.

　　The Implementation Guide for COVID-19 Nucleic Acid Testing Organization (Second Edition) clearly stipulates the preservation and transportation of samples, which should be kept at low temperature (2-8 degrees Celsius). In principle, samples should be collected every 2 hours for transportation, and the samples should be delivered to the laboratory 4 hours after collection.

　　On the basis of the above guidelines, Shanghai has further put forward "126" requirements for nucleic acid testing institutions, that is, collecting and transporting a batch of samples every hour, transporting the samples to the testing institutions in 2 hours by vehicles, and completing the testing in the laboratory within 6 hours. In terms of sample transfer, the time requirement is reduced by half compared with the guideline, but in fact, it is very difficult to achieve such a goal. If the sample is not transferred in time, it will not only affect the quality of the sample, but also affect the waiting time for detection.

　　In this regard, the above-mentioned infectious disease experts told the First Financial Reporter: "Since there are norms, it should be strictly implemented in accordance with the norms. For example, it is stipulated that samples should be shipped every hour or two, and someone should come to pick them up when they arrive, instead of seeing that there are enough people to pick them up. If not, just wait."

　　The expert also warned that as the weather gets hotter, if the nucleic acid reagent cannot be stored at low temperature in time during transportation, or exposed to the sun for a long time, it will increase the risk of inaccurate nucleic acid test results.

　　He told the First Financial Reporter: "You should know that ribonuclease is ubiquitous. It exists in the air and anywhere. When you open the lid of the nucleic acid test tube, it may enter the test tube. At the temperature above 37 degrees, Rnase will easily degrade RNA, and the whole process only takes 10-15 minutes. If there is a very low virus load in the test tube, it will be diluted after ten mixes.

　　According to the observation of the first financial reporter at some nucleic acid detection points, in some mixed-tube tests, the actions that do not meet the operating standards include picking a person without screwing on the cover, which also increases the risk of exposing the sample to the air.

　　The above experts added that although adding some components, such as diethyl pyrocarbonate (DEPC), to the reagent can help to inhibit Rnase, these components will increase the cost of the reagent, and standard nucleic acid reagents are generally not added. "The easiest way is to keep it at low temperature and transport it in time. Even using ice cubes to cool down is helpful. Ice cubes have no cost and can be reused." He told the first financial reporter.

　　He also stressed that the basic operation in transferring samples is to put the samples into two-layer sealed packages and avoid the test tubes from tipping, so as to prevent the reagent from leaking and polluting other samples because the cover is not tightened.

　　Professor Lu Hongzhou, president of Shenzhen Third People’s Hospital, told the First Financial Reporter: "The best way to solve this problem is to collect samples regularly."

　　Professor Shen Hanming, an expert in cell biology at the University of Macau, told CBN: "In theory, there is a protective solution in nucleic acid reagents, and some components can inhibit RNA degradation to a certain extent, but even so, in principle, reagents should not be stored at room temperature and high temperature for a long time."

　　In order to activate the new kinetic energy of high-quality development of township economy, and further consolidate the effective connection between the achievements of poverty alleviation and rural revitalization, Nankang District of Ganzhou City takes "a prosperous town for the people" as the goal, takes economic development as the main line, takes the development of private economy as the starting point, and focuses on key tasks such as enterprise cultivation, industrial transformation and upgrading, and financial system reform, so as to give full play to the positive role of fiscal policy, fully improve the level of township economic development, and promote the sustained, rapid and healthy development of township economy.

　　First, focus on supporting and promoting the first industry.Focusing on the first industry of modern home furnishing, we will improve quality and efficiency, play a positive role in fiscal policy, better guide all towns (streets) to adhere to standards guidance and innovation drive, manage and operate furniture gathering areas, actively promote the overall improvement of environmental protection, fire protection and safety production in the region, and further promote the transformation and upgrading of the first industry of home furnishing.

　　The second is to vigorously cultivate and expand market players.Support each township (street) to cultivate new leisure agriculture such as industrial enterprises above designated size and farmhouse music based on local characteristics. Strengthen departmental cooperation, increase policy propaganda, optimize the approval process, actively guide foreign business workers to return home to start businesses, and continuously enhance the new kinetic energy of town economic development.

　　The third is to deepen the pilot reform of the township financial system.Implement the relevant arrangements for the reform of the financial system below the provincial level, in accordance with the principle of "checking revenue and expenditure, striving for self-balance, and encouraging development", and on the basis of scientifically delineating the base of township financial revenue and expenditure, further clarify the scope and sharing ratio of district and township income, standardize the sharing of surplus income, give full play to the financial enthusiasm of district and township levels, and strengthen the guarantee ability of financial assistance to township economic development.

　　In addition, policies and measures should be refined in promoting new urbanization, and performance appraisal should be increased to ensure the sustained and healthy development of township economy.

CCTV News:Tomorrow (June 22nd) is the Dragon Boat Festival holiday. The reporter learned from china tourism academy that this year’s Dragon Boat Festival holiday, the number of tourists is expected to exceed the level of the same period in 2019, reaching 100 million, and the holiday trips will mainly focus on Zhou Bianyou and short-distance tours.

Following the unexpected release of the "May Day" labor holiday tourism demand, the market demand for Dragon Boat Festival holiday tourism is in a warm period. The reporter learned from a number of platforms that during the Dragon Boat Festival holiday this year, the average price of hotels and air tickets in China and many popular destinations will be lower than that during the May Day holiday. Beijing, Hangzhou, Guangzhou, Chengdu and Qingdao will become popular tourist destinations in China.

Dai Bin, Dean of china tourism academy:We predict that there will be 100 million people traveling during the Dragon Boat Festival holiday this year, and there will be 37 billion yuan in tourism consumption. What does this data mean? This means that compared with the same period last year, the number of tourists will increase by 30%, while tourism consumption will increase by 43%.

China tourism academy predicted that tourists from Guangdong-Hong Kong-Macao Greater Bay Area, the Yangtze River Delta, Beijing-Tianjin-Hebei, the middle reaches of the Yangtze River and Chengdu-Chongqing urban agglomerations will circulate and interact, and a "three-hour golden tourism circle" will be formed around major tourist cities, and the popularity of tourist resorts such as Beidaihe, Songshan and Conghua will gradually become apparent.

Dai Bin, Dean of china tourism academy:Because (Dragon Boat Festival holiday) only lasts for three days, compared with "May 1" Labor Day (holiday), it is mainly short-distance travel, mainly in Zhou Bianyou; Self-driving, individual travel, family, parent-child, study and summer vacation will become the key words of holiday travel.

Shunde, Guangdong: Colorful boats compete for beauty to welcome the Dragon Boat Festival "Night Dragon Tour"

It is also a traditional festival of Dragon Boat Festival, with dumplings and dragon boat races, which has long been a lively scene all over the country. This year, the dragon boat race held in Shunde is unique and eye-catching. What kind of dragon boat race is it? Now let’s take a look with the reporters at the reception desk.

General Station reporter Qu Baiyu:This is Ronggui Street in Shunde, Guangdong. Usually, people watch dragon boats faster than others. Today, I want to show you Bimei.

At the competition site, gongs and drums were loud, waves splashed and dragon boats fought brightly. Ten dragon boats from various clubs in Rong Gui decorated their bodies with gongs and drums, umbrellas and colored lights, and they "dressed up" for a trip to show their slender posture. "Night Dragon Tour" is rare in Guangdong, which is a unique feature of traditional dragon boat culture in Rong Gui. Different from the traditional Youlong, the night dragon with lights in Rong Gui not only retains traditional elements such as gongs, drums and umbrellas, but also uses LED lights to decorate the dragon boat, innovating the form of dragon boat competition, and skillfully blending water, lights and music.

Putian, Fujian: colorful folk customs of "dragon boat climbing" at sea welcome the Dragon Boat Festival.

As the Dragon Boat Festival approaches, Fujian will carry out special folk activities in many places. These two days, in Dongpu Town, Putian City, a huge sea dragon boat race was staged.

In Putian, Fujian, dragon boat racing is also called "dragon climbing boat". On the morning of 19th, Jicheng Village, Dongpu Town, Putian City ushered in a lively Dragon Boat Climbing. On the sea, the dragon boat players follow the rhythm of drums and raise their arms to paddle hard. On the beach, citizens and tourists shouted for fun, and the scene was crowded and lively.

Tourist Liao Kajia:I like watching the Dragon Boat Festival in China very much, because it is very lively and crowded, and it is very comfortable to watch together.

According to reports, during the Dragon Boat Festival, in addition to the dragon boat race at sea, villagers in Jicheng Village will also hold dragon dances and flower drums, and the folk performance team consisting of thousands of people will stretch for miles, which is very spectacular.

Putian citizen Li Jianhuang:We rushed back to our hometown from Yunnan for the traditional Dragon Boat Festival, and we were very happy. One is to unite everyone’s cohesion, and the other is to carry forward traditional culture.

It is understood that Putian has a wide range of rivers and waters, and the Dragon Boat Festival is the most important local folk activity every year. This year, Putian Dragon Boat Race Folk Games will span many counties and districts and will last until the beginning of July.

Henan Dragon Boat Festival: Drum-beating and Paddling Dragon Boat Race for the Dragon Boat Festival.

With the approach of the Dragon Boat Festival, a Dragon Boat Culture Festival was held in Zhumadian City, Henan Province these days, and everyone welcomed the Dragon Boat Festival by way of dragon boat race.

At the Dragon Boat Culture Festival in Zhumadian City, Henan Province, the 200-meter straight race and the 300-meter straight race were set up in the dragon boat competition. On the field, drums were rumbling and cheering, and Qi Xin, a 12-player dragon boat team, joined forces to paddle and cut waves and compete. The dragon boat race attracted many citizens and tourists to watch it. People took pictures by video and recorded wonderful moments.

Meng Xin ‘ai, a citizen of Zhumadian, Henan:Everyone wants to stick to the traditional culture, so everyone is very supportive of this movement and hopes to hold more such activities in the traditional culture in the future.
