Before signing the contract, Mo Mo’s sister A Leng’s ultra-luxury anchor lineup gathered in Betta.

On June 24th, a Weibo by A Leng, the former anchor of Mo Mo, caused quite a stir in the live broadcast field. After a two-month hiatus, A Leng announced his return to his fans and will join DouYu.

heavely sound+Versatile and sweet girl with huge fans

As one of the most popular anchors of Momo, A Leng earned an annual income of 16 million yuan in 2016, and even created a miracle in the live broadcast industry that was rewarded with 30 million yuan in eight months. She is comparable to a first-line star and is a well-deserved sister of Momo. After graduating from a famous university, she also went to teach at the Confucius Institute in the United States in 2014. Not only did she get excellent grades, but A Leng also had an unusual talent in playing musical instruments. Both erhu and guitar won prizes in the competition.

A Leng looks sweet and has a voice that surprises people. In the colorful metropolis, she did not choose to go with the flow, refused to rely on her face value, and attracted a large number of diehard fans with her hard work and sincere singing. In the live broadcast world, A Leng is known as "online celebrity Clean Stream" and "talented female anchor". Compared with other female anchors in online celebrity, A Leng’s route is obviously different from theirs, with outstanding temperament, elegant clothes, cordial communication with fans, and singing one song after another. Just like this, A Leng’s live broadcast received a flood of praise, and more and more people began to pay attention to it.

High-quality platform holds hands with popular anchor DouYu and adds the top singer.

It is understood that A Leng’s first test of water in Betta attracted people to watch. On the day of registration, there were even more local tyrants who brushed gifts with black screens, which once made A Leng advance to the fourth place in the Betta anchor’s earnings weekly list before broadcasting. Interestingly, the area where A Leng lives in Betta is actually the League of Legends game area. A Leng’s strong joining will pose no small threat to Ti mo Feng, a betta sister in the League of Legends area, and Chen Yifa, a sweet singer.

It is understood that Ti mo Feng and Chen Yifa have 3.6 million and 2.3 million fans in Weibo, respectively, but there is still a certain distance between Alang’s 120,000 Weibo fans and the two major anchors. From this set of data, we can easily see that betta fish plays an important role in it, and the platform with wider coverage and stronger influence will greatly enhance the popularity of the anchor. I believe that the growth rate of the number of fans in Weibo will also become one of the concerns after Alang enters Betta.

The anchor camp shuffled and reorganizedBetting platform becomes the biggest winner

With the rapid development of the live broadcast industry, the participation of the whole people has become an indisputable fact. Under the hot situation of live broadcast, serious homogenization is rampant. If we want to fight our way out in the homogeneous industry, we must develop the platform competitiveness in an all-round way from multiple dimensions. For the live broadcast platform, it has become the core competitiveness to build a live broadcast platform by leading users and content anchors. The strong joining of Alun this time, its own strong flow will definitely bring a new round of "bombing" to Betta.

Ah Leng’s joining may not come as a surprise to the water lovers of fighting fish. Before Ah Leng, there was a girl named "Natto", a secondary oxygen girl, who was called bilibili’s first sister, who settled in fighting fish. With the birth of online celebrity’s economy, the competition of platforms for anchors is becoming increasingly fierce, but more and more anchors pay more attention to the platform quality and development prospects. Known by the industry as "the Whampoa Military Academy in the anchor field", after a group of anchors, such as Fu, Ti mo Feng and Yifa Chen, have grown into first-line online celebrity, the addition of A Leng has also started a new round of reshuffle and reorganization of the anchor camp in the industry, and Betta has gradually become the biggest winner in the live broadcast field with its strong anchor lineup and high-quality content. Today, with the rapid development of live broadcast platforms, more and more anchors will choose platforms with better user base and broader development prospects. It is not surprising that fighting fish will have more fresh blood injected.

It is reported that A Leng will start broadcasting in Betta at 21:00 on the evening of 27th, and we will wait and see what surprises she will bring us.

How far is L3 autopilot from us?

As we all know, the "second half" of the new energy vehicle market will be an intelligent competition. Near the end of the year, the domestic city NOA Kaicheng War intensified, and L3 test policy boots officially landed. On December 22nd, Changan Automobile announced that it had successfully obtained L3-level self-driving road test licenses for 17 expressways on November 17th, becoming the earliest enterprise to obtain such licenses at most in a single batch. How far is L3 automatic assisted driving?

"Made in Chongqing" car starts L3 road test.

A few days ago, China’s Ministry of Industry and Information Technology and other four ministries and commissions jointly issued the "Notice on Launching the Pilot Work of Intelligent Networked Vehicle Access and Road Access", which formally set specific requirements for L3/L4 autopilot access specifications and improved relevant rules. This means that China’s advanced autonomous driving has a clear policy support and responsibility definition.

The introduction of the new policy has opened the floodgate of mass production for the long-awaited smart car industry.

As of December 21st, 17 L3 self-driving vehicles of Changan Automobile have passed the 34-day road test. The L3 self-driving road test was carried out in Chongqing Inner Ring Expressway. The total length of this section is 74.1km, which is very mountainous, covering complex scenes such as construction, long slopes, continuous bends, bridges, tunnels, ramp entrances, etc. The traffic volume is large, with the maximum one-way cross-section traffic of 94,000 vehicles/day and the maximum peak traffic of 7,300 vehicles/hour. The whole section has normal traffic jams in the morning and evening peaks.

According to relevant sources of Changan Automobile, the traffic jam autopilot function of Changan Automobile has undergone a severe test in this road test.

At the same time, a number of "Chongqing-made" cars have also made great efforts in high-speed and urban NOA(Navigate On Autopilot). It is generally believed in the industry that the urban NOA is approaching L3, which is a crucial step from L2 to L3. In short, if you want to go from place A to place B, you only need to enter place B in the navigation, and you can hold the steering wheel to supervise how the vehicle waits for the traffic lights, changes lanes and gives way in the covered area.

On October 9th, Aouita Science and Technology announced that it would gradually open the NCA without map, and intensively carry out large-scale actual road test and user experience. As the core capability of Huawei’s advanced intelligent driving system ADS 2.0, Aouita has taken the lead in covering six cities, namely Beijing, Shanghai, Guangzhou, Chongqing, Shenzhen and Hangzhou, and the second batch of functions will cover another 16 core cities, with full coverage in China within this year.

The world under the banner of Celestial Automobile was the first to open the push of the city NOA. In July this year, the urban NCA function of the M5 Zhijia version was opened in five cities: Shanghai, Shenzhen, Guangzhou, Hangzhou and Chongqing. In December, the new M7 in Wenjie was equipped with HUAWEI ADS 2.0 advanced intelligent driving system, and the high-speed NCA intelligent driving navigation auxiliary function of the vehicle can be used nationwide without relying on high-precision maps.

Yu Chengdong, managing director of Huawei, CEO of terminal BG, and chairman of smart car solutions, mentioned in the latest order "Battle Report" published on social media in October that the selection rate of high-end packages of M7 five-seat Max version ADS was 70%, and that of six-seat Max version ADS was 68%.

The NOA timetable of car companies has been released one after another.

The competition for the city NOA is not limited to "Made in Chongqing".

On March 31st, 2023, Tucki fully promoted XNGP (Full Scene Assisted Driving) version 4.2.0, and all users of G9 MAX and P7i MAX can get this software version.

He Xiaopeng, CEO of Xpeng Motors, said, "We promise that the first city in China will drive Kaicheng &hellip in 25 cities by the end of November; …”

Subsequently, brands such as Ideal, Weilai and Zhiji have also announced the specific timetable of the city NOA. This means that it has completed 50% of the progress bar of the goal of opening a city in 50 cities.

In addition, Xpeng Motors has publicly stated that the Max version of Tucki G6 has an optional rate of over 80%, and the Max version of Tucki G9 has an optional rate of over 80%.

Recently, Li Xiang, CEO of LI, said on the social platform that the official version of NOA in December covers the national expressway and ring road and 100 cities, and the LCC function will be available worldwide.

Weilai also officially opened the test of NOA function in Shanghai in June.

On December 16th, Zhiji Automobile announced that its vehicles equipped with L3-level automatic driving function have officially obtained the high-speed highway automatic driving test license in Shanghai. At the same time, Zhiji is applying for the L3 announcement access pilot of the Ministry of Industry and Information Technology, and it is expected to be the first vehicle to enter the L3 autopilot access pilot.

On December 12, Gu Huinan, general manager of Guangzhou Automobile Ai ‘an, revealed: "Ai ‘an is applying for L3 autopilot together with Ruqi Travel, and strives to be the first to launch truly operational L4 autopilot in 2025."

On December 16th, Mercedes-Benz became one of the first enterprises to obtain the road test license of Beijing Conditional Autopilot (L3) Expressway. Two days ago, China’s first L3 test license was spent on BMW — — BMW announced that it has obtained the L3-class self-driving high-speed road test license in Shanghai.

Mercedes-Benz has made it clear that after Germany and the United States, it will promote L3-class autopilot system Drive Pilot in China market, and BMW Group plans to officially launch L3-class autopilot function in late 2023 or early 2024.

In August this year, Tesla CEO Musk revealed that Tesla is developing the last puzzle "Vehicle Control" of the FSD V12. The automatic driving system adopts an end-to-end solution. In November, Tesla has pushed the FSD V12 to employees.

The ideal NOA, NGP of Tucki or NCA of Huawei, under the influence of a dazzling array of technical terms, the "second half" of intelligent driving is really coming.

How far is L3 autopilot from us?

At the end of 2023, L2′ s driving function was gradually optimized. How far is L3 from us?

At the 5th China Automobile and Travel Future Forum, data show that at present, the penetration rate of intelligent driving above L2 will exceed 40%.

Many domestic progressive autonomous driving companies are also realizing data closed loop through mass production and high-order assisted driving scenes, and promoting the rapid maturity of autonomous driving technology; In addition, many key cities in China are also accelerating the construction of "smart cities", delineating pilot areas and promoting the coordinated construction of vehicles and roads.

It is understood that in terms of chips, NVIDIA leads the iteration of smart driving chips, Mobileye and TI technologies are mature, and the distance between domestic players Horizon and Black Sesame is gradually shortened. In terms of domain controllers and solutions, domestic players Desai Siwei, Jingwei Hengrun, Zongmu Technology, Zhixing Technology, etc. have all got on the bus on a large scale, and their technical maturity has been continuously improved. Laser radar: domestic suppliers such as Wo Sai, Tu Datong and Sagitar have a faster pace of mass production.

On November 26th, Hu Yang of Huaxi Securities pointed out that as of August, 2023, the country had opened more than 20,000 kilometers of test roads, and a large number of intelligent networked automobile products were developed, tested and verified. The opening of this pilot will help the intelligent networked vehicles to accelerate the technical level, and also accelerate the industrialization process of the smart car industry. L3/L4 smart driving will also accelerate its landing next year.

As a watershed between assisted driving and driverless driving, L3 autopilot needs not only technical support, but also coordinated support from policies, legislation, infrastructure and other aspects.

Last August, the first domestic regulation on intelligent networked vehicle management — — The Regulations of Shenzhen Special Economic Zone on the Management of Intelligent Networked Vehicles was officially implemented. This legislation is the first official management document in China to divide in detail important issues such as the rights and responsibilities of L3 and above automatic driving, and provides a policy basis for self-driving vehicles to legally go on the road. Although it is only exclusive to Shenzhen Special Economic Zone, its significance to the national intelligent networked automobile management legislation is self-evident.

The promulgation of the "Notice on Launching the Pilot Work of Intelligent Networked Vehicle Access and Road Access" has further accelerated the landing of high-level automatic driving.

In the current upgrade war of autonomous driving, mass production capacity is the "key" to cross L2 to L3. According to the above-mentioned Notice, the emphasis on mass production capacity again means that players without mass production capacity can’t even get "admission tickets".

Changan Automobile said that it will continue to pay close attention to the requirements of China regulations and, with the support of policies and regulations, will introduce L3-class autopilot function to the market at an appropriate time.

According to the data released by the Industrial Research Institute, it is estimated that the penetration rate of L3, a new car on sale, will reach 20% in 2023.

According to the agency’s forecast, in 2024, the urban NOA layout process will rapidly expand to 100 cities across the country, and the sales volume of NOA models will reach more than one million.

Upstream journalist Yan Wei

Xpeng Motors Zhijia team lost another general.

Today, it is reported that Liu Yilin, senior director of Xpeng Motors Autopilot Products, will leave his post. At the same time, it is said that he will join NVIDIA and join Wu Xinzhou, former vice president of Tucki Autopilot.

In this regard, Liu Yilin himself wrote that any "joining other enterprises" at present is false information.

In August, 2023, Wu Xinzhou, the former vice president of autonomous driving in Tucki, left Tucki and joined NVIDIA as the "global vice president", reporting to Huang Renxun. According to media reports, after Wu Xinzhou left his post, the responsible persons of autonomous driving, including perception, decision-making and lidar, also left one after another.

It is understood that Wu Xinzhou is the core figure of Xpeng Motors’s autonomous driving business and once served as the vice president of Xpeng Motors’s intelligent driving business. He joined Xpeng Motors in March 2019 and was fully responsible for the autonomous driving business and team management. Wu Xinzhou graduated from Tsinghua University and received his master’s and doctor’s degrees in electronic engineering from the University of Illinois at Urbana-Champaign. Before joining Tucki, he was the head of the autonomous driving R&D team in Qualcomm.

According to Wu Xinzhou himself, he left his job because of family and various reasons, and he said that he would return to the United States. He Xiaopeng also mentioned that Wu Xinzhou expressed this intention in the second half of last year.

Wu Xinzhou’s departure is an important change for Xpeng Motors. During his stay in Xpeng Motors, he promoted the rapid development of the company’s autonomous driving technology, including self-developed intelligent driving software algorithms, and promoted Xpeng Motors to become a leading domestic autonomous driving technology enterprise. His departure may have a certain impact on Xpeng Motors’s autonomous driving business.

[CCTV Review] Where does the real-name report of car violations come from? Is it reasonable and legal?

△ Wuhan City’s vehicle illegal parking in August. The picture is from Ping An Wuhan

  I believe many people have experienced similar scenes. In order to manage illegal parking, many cities have carried out special rectification of illegal parking of motor vehicles. The Wuhan Traffic Management Bureau recently released,From now until December 31st, there will be a reward for reporting illegal parking on roads in the central city of the city, with a maximum reward of 5,000 yuan.

  Award criteria:

  According to the circular, the traffic control department will conduct monthly statistical ranking on the number of effective illegal parking reports to the public, and give classified rewards to the top 150.

  Number of top 10 and effective reportsMore than 600Per person5,000 yuanReward

  Number of effective reports ranked 11th to 50th.More than 400Per person2000 yuanReward

  Number of effective reports ranked from 51 to 150Over 200 casesPer person1000 yuanGive a reward.

  Informants need real-name authentication.

  Informants need real-name authentication, and the photos provided (three photos that meet the requirements)., should be able to clearly display the illegal vehicle type, license plate number, appearance characteristics, illegal behavior, illegal location, illegal time and other effective information.For the same illegal act reported by many people, the first whistleblower will be rewarded according to the time sequence of reporting registration.

  Not only Wuhan, but also some cities have launched a reward report on traffic violations before. 

  Shenzhen:

  Shenzhen traffic police issued a report bonus of 1.36 million yuan in two years.

  In December 2013, the Shenzhen Traffic Police officially launched a prize-winning report on road traffic violations in the city. As of December 2015,A total of 35,630 reports of various traffic violations were received, and bonuses of 1.36 million yuan were issued. 

  General violations are included in the scope of reward reporting.

  Shenzhen traffic police recently said that they decided to include general illegal acts in the scope of reward reporting.100 yuan will be rewarded for reporting traffic accidents or traffic jams caused by illegal parking.

  Hangzhou

  The highest reward 100 yuan does not include violations.

  In March 2016, Hangzhou Traffic Police launched a reward mechanism for reporting key traffic violations and clues. Mainly aimed at 18 kinds of dynamic and hidden traffic violations in three categories, The highest reward is 100 yuan.. It should be noted that the scope of the trial reward report is the road within the main urban area of Hangzhou. At the same time,18 kinds of illegal acts do not include violations.

△ Hangzhou tries to report traffic violations with prizes. Citizens can be electronic policemen themselves.

  How effective is the "reward report"?

  Wuhan: Only 40 of the 1,800 photos and video traffic violation reports passed the preliminary examination.

  Since August 15th, Wuhan has reported four types of traffic violations with prizes. By the beginning of September,The citizens submitted 1839 pictures and videos reflecting four types of traffic violations. After preliminary examination, only 40 reports were "qualified".Most of them lack the elements needed for punishment.

  Will the reward for reporting traffic violations make the chaos of illegal parking better? Is it a perfect solution to report illegal parking with real name? Where does the reward for reporting come from? Is it reasonable and legal? Is there any legal risk?

Cctv review

  For a long time, illegal parking is a difficult problem in the management of many cities in China. According to official data, the number of private cars in China reached 86.5 million in 2012.There are 20 cars per 100 families.It has become an "automobile society" in the sense of international standards. However, the rapid growth of private cars has also brought serious congestion, disorderly parking and other quite headache problems. If we want to solve the problem, we really need to "enlarge the trick".

  There can be prizes for reporting, so you should use them with caution.

  In daily management, the traffic police departments in many cities are faced with the problem of insufficient manpower.Wuhan adopts the method of mobilizing the masses, so that every citizen can become a supervisor of civilized parking and a whistleblower of illegal parking, which can not only assist the police in law enforcement, but also give play to the spirit of urban ownership of the general public. In fact, some violations also hinder the normal life of many citizens, and it is reasonable to report them.

  From this perspective, reporting traffic violations is conducive to people’s participation in law enforcement. There can be, butOnce the report is involved with the "prize", it will increase the utilitarian color and easily lead to new problems.. Reward reporting is a double-edged sword and should be used with caution.

  First of all, according to the rules of Wuhan, the traffic control department will give classified rewards to the top 150 people who report illegal parking with real names, whichWhether the implementation will lead to a large number of people complaining and reporting in the first few days of each month, and the rest of the time will make the public lack the motivation to report.

  In addition, members of the public are encouraged to report crimes in order to assist law enforcement. However, in the process of reporting, each whistleblower also needs to provide corresponding photos and evidence.For such reporting materials, it is also necessary to arrange manpower for verification and verification, so that the punishment is justified.This also brings new manpower demand and work pressure. Whether the cost of law enforcement has dropped is unknown.

  More importantly, rewarding citizens for reporting will inevitably breed "reporting professionals".If the reward report is abused, the whistleblower will bet all his money on the prize, and the result may lead to the prevalence of "fishing".There have been cases where a professional photographer deliberately violated the rules, and on the difference between reporting bonuses and simple violations, he started an illegal farce of "one willing to fight and one willing to suffer" to deceive the traffic control department.This kind of behavior undermines the due process of law enforcement and distorts the original intention of law enforcement. In addition, the problems brought by professional counterfeiting are also a lesson from the past.

  Encourage the reporting of traffic violations and prevent legal risks.

  The law cannot be done without authorization. In a modern society ruled by law, any force participating in social governance must take legitimacy as the basic premise.According to Article 47 of the Procedures for Handling Administrative Cases by Public Security Organs: "Public security organs shall promptly accept cases of reporting, accusing, reporting, being turned over by the masses or surrendering illegal suspects, and cases transferred by other administrative departments and judicial organs … …” .Informants subjectively report illegal acts and objectively provide the illegal information to law enforcement agencies. If it is not used for other purposes and is not disseminated in public media,Even if the reported person is punished by law enforcement agencies for the relevant reporting clues, it does not constitute infringement in the sense of civil law.

  But in reality, the introduction of every policy will have certain risks. In the process of reporting traffic violations, people face some legal risks.For example, will it cause information leakage (there are countless problems of personal information leakage now), will there be informants using mobile phones to shoot evidence while driving, or will they be in danger when shooting evidence, and so on.This requires law enforcement agencies to design in advance when formulating policies.

  Bonus distribution should be open, objective and fair.

  Once the issue of bonus payment is involved, utilitarian chips are added. Where does the money to reward the people come from? How to distribute it?For example, who was rewarded for reporting what kind of violations? All these should be done.Information is open, objective and fair, and black-box operation is prevented.Moreover, in this process, how to protect the information of the whistleblower and how to effectively protect the whistleblower’s information while making it public need to be carefully arranged.Practically there are laws to follow and rules to follow.

  In addition, what is the effect of the reward-reporting measures? The masses took a lot of photos to report traffic violations, but what was the adoption rate? Can it effectively alleviate road traffic problems? These problems are worth thinking about.If, after the report, the violation of the regulations does not improve, but the resulting fines increase, this may cause the public to question the real purpose of this move.After all, there is basically no public account of where a large number of traffic violation fines go every year.

  Traffic management is a big project, which also includes the management of static traffic. It is of course necessary to punish illegal parking effectively, but at the same time, it should be effectively diverted. How to make a better plan, how to increase the effective supply of parking spaces, and whether the use efficiency of parking spaces can be gradually improved are all related to the effect of our control of parking and misplacing.Reward reporting is not a normal law enforcement, and a society ruled by law needs normal law enforcement. It is expected that a series of combination boxing will be introduced, supplemented by rigid punishment and law enforcement, and the phenomenon of parking will finally be effectively controlled.

What is it that makes the US military win the treasure! This technology makes everything possible?

       CCTV News:"The U.S. military regards quantum computing as a key weapon in the space war", which is the title of a report of the U.S. Space Network on July 15th. A few weeks ago, senior Pentagon officials began to discuss with scientists the future of quantum computing in the US military. What is quantum computing? Why is the United States waiting for it?

       On June 27th, 2018, the Committee on Science, Space and Technology of the U.S. House of Representatives passed the National quantum scheme Act, announcing that it will invest 1.3 billion U.S. dollars in 2019 -2023 to conduct state-level quantum technology research.

       On November 10th, 2017, IMB announced that it had successfully developed a quantum computer with 20 qubits. In addition, IBM has successfully developed the world’s first 50-bit qubit prototype.

       If the superpowers mastered nuclear technology in the 20th century, they would gain global hegemony. Then in the 21st century, a big country that has mastered quantum technology is called "quantum hegemony" by Preskill, a theoretical physicist at California Institute of Technology.

       In 1936, alan turing, the "father of computer science", submitted a paper entitled "On the Application of Digital Computing in Solving Difficult Problems" to the authoritative mathematical magazine in London. In the paper, an idealized computing model which can assist mathematical research was proposed, and it was later called Turing Machine. By using the permutation and combination of pure digital symbols 0 and 1, the connection with the physical world was established, and later this concept was applied to computers and became the core of modern computers.

turing

       Over the past 80 years, although computers have become smaller and faster, and the memory has become larger and larger, the basic core has remained unchanged. Until 2010, D-Wave, a company located in Vancouver, Canada, launched the world’s first commercial quantum computer, D-Wave One, which won the title of "revolution".

       Traditional computers use the smallest unit "bit" of binary data to process information. Each bit represents a binary digit, which can represent 0 or 1. These 0′ s and 1′ s, like switches, finally constitute calculation data for a simple operation. For example, to solve a maze, the traditional computer will try every possible route one at a time and finally find the right one. The method of quantum computing is completely different. Quantum computers use quantum bits and make use of the two principles of quantum superposition and quantum entanglement in quantum physics. Compared with electronic bits, quantum bits are fuzzy. That is, a thought experiment "Schrodinger’s cat" often mentioned in physics.

       To better understand how quantum computers work, let’s give an example from life. Imagine a library. We choose a book in the library, put a cross on one page of the book, and then close the book. Then we asked the traditional computer to find this fork in the book. Traditional computers will look at page by page, and they will soon find the page with the cross. But if the computer doesn’t know which book the fork is in, it must look at every page of every book, which will take a long time. If it is to find the fork on that page in all the millions of books in the world, it will take centuries for traditional computers and it is almost impossible to achieve it. But if there is a quantum computer, it is completely different. Because it can search all pages in all books at the same time, it can find this fork in a few seconds.

       The running technology on the traditional computer can skillfully find the rules buried in the massive information, but the quantum computer can give the answer when there is not enough information or too many solutions to find the rules.

       The huge difference between quantum computer and traditional computer in operation enables it to perform operations that traditional computers can’t do, and it can even solve some complex problems that the most advanced supercomputers can’t solve.

       Andrew Foresman and Langdon Downs founded the 1Qbit startup company six years ago, and convened the global "super brain" to build quantum software. This idea is being realized step by step. Foresman said that quantum computers may simulate the human world in the future.

       In the American sci-fi drama westworld, by copying and simulating people’s thinking, bionic people are created to continue their lives. More subtly, this kind of simulation and replication is not fixed, but slight defects may occur randomly. The origin and evolution of species are also due to unpredictable "defects" in the genetic process. This is also the key difference between machines and humans.

       With quantum technology, everything is possible.

       However, the conditions of quantum effect are very strict, and it is necessary to cool the quantum chip to near absolute zero with liquid helium, which is about equal to MINUS 273.15 degrees Celsius to run stably.

       In the future, the convenience brought by quantum computing technology will not only be reflected in life, but also contribute to the military.

       Canada’s Super Invisible Biotechnology Company claims to have developed a "quantum invisibility cloak", just like the invisibility cloak worn by Harry Potter, which can make the wearer "disappear" in people’s sight instantly. This kind of camouflage materials can bend the light, which can not only "cheat" the naked eye, but also be invisible under the detection of military night vision goggles, infrared rays and thermal imaging technology. Camouflage materials, a Canadian super stealth biotechnology company, was quickly recognized by the US military and gave the company a lot of financial support for subsequent research and development.

       At present, many countries have begun to study quantum computing technology.

       On August 16th, 2016, China successfully launched the "Mozi" quantum science experimental satellite. The US Space Network reported that the satellite adopted quantum secure communication technology and became an "invulnerable" satellite.

       Britain is planning a $400 million sensing and timing project based on quantum technology; A similar project in the EU is expected to invest $1 billion in 10 years; Canada, Australia and Israel also have considerable plans.

       In the early 1990s, Elizabeth Berman, a physics professor at Wichita State University, began to study the combination of quantum physics and artificial intelligence. But at that time, most people questioned this. Nowadays, artificial neural network and machine learning have become the most subversive technologies. They not only appear in tasks that humans are not good at, such as data mining, but also begin to appear in tasks that humans are good at, such as facial recognition. This means the personification of artificial intelligence. If quantum computing is used, it will completely solve all kinds of problems faced by artificial intelligence, and the future quantum war will really challenge the human brain.

Internet use for minors: from entertainment to entertaining.

  On February 27th, 2023, the Central Committee of the Communist Party of China and the State Council issued the Overall Layout Plan of Digital China Construction (hereinafter referred to as "the Plan"). The Plan points out that speeding up the construction of digital China is of great significance and far-reaching influence on building a socialist modern country and promoting the great rejuvenation of the Chinese nation in an all-round way. The Plan also points out that it is necessary to strengthen the supply of high-quality online cultural products, guide various platforms and netizens to create and produce positive, healthy and upward-oriented online cultural products, and further promote the digital development of culture and implement the national cultural digital strategy. Teenagers are the vanguard force to realize the great rejuvenation of the Chinese nation, the new force to achieve the goal of the second century and build a socialist modern power, and they can’t be absent from the overall layout of the construction of digital China. It is one of the core essentials of the construction of digital China to let minors enjoy the universal and convenient digital culture and get high-quality development in the digital society.

  According to the "Research Report on Internet Use of Minors in China in 2021" (hereinafter referred to as "Report") issued by the Central Rights and Interests Department of the Communist Youth League and China Internet Information Center, the top five online use behaviors of minors are online learning (88.9%), listening to music (63.0%), playing games (62.3%) and chatting (53.4%). It can be seen that minors mainly use the Internet for learning and entertainment, especially through the Internet. According to the report, nearly 40% of minors learn extracurricular knowledge through the internet, and more than 70% think that the internet is helpful for learning. This shows that the internet use of minors is gradually changing from "toys" to "tools" and from entertainment to knowledge.

  Karl Mannheim, a German sociologist, believes that knowledge is characterized by openness and mobility in the process of modern society. The knowledge of short video platform broke the knowledge barrier, changed the linear and self-contained characteristics in the past, and showed the characteristics of networking and knowledge sharing. Through the reorganization and transformation of knowledge, it creates a learning space and platform with diverse contents and rich forms for people, which makes the boundary of knowledge learning in the digital age more extended and integrated, and serves the minors and provides them with an important channel to broaden their horizons and increase their knowledge. The short video is visual, scene-oriented and practical, which is more in line with the cognitive law of minors. Therefore, the Report also shows that nearly half of minors study through short video platforms. Among them, 34.0% are primary school students, 61.8% are junior high school students, 65.1% are senior high school students and 64.7% are secondary vocational school students. It can be seen that the proportion of minors over 12 years old who are exposed to short videos is higher. Minors watch short videos of learning knowledge such as exam counseling and classroom knowledge, accounting for nearly 40%, and watch short videos of interest knowledge such as piano, chess, calligraphy and painting, historical geography, sports and dance, and watch short videos of leisure knowledge such as tourism and food, accounting for nearly half. Moreover, short video platforms such as Tik Tok have also become the main channels for minors to expand their cognition.

  Facing the brand-new learning style of minors in the digital age, how to use short videos scientifically and reasonably has become a new topic for family rearing and school education in the digital age. Some parents worry that their children are addicted to short videos, but psychological research believes that addictive behavior needs six elements: goal, feedback, progress, challenge, suspense and socialization. That is to say, users are more likely to be addicted if there are six elements in the process of using a product: having a goal, getting feedback in time, getting rewards frequently, constantly encountering new challenges, uncertain results and having social attributes. Moreover, whether it is addictive or not is closely related to the user’s living conditions, psychological conditions, interpersonal relationships and family upbringing. Although short videos have increased people’s sensory experience more comprehensively than words or pictures, they also have social and entertainment attributes, but they do not have these six elements at the same time. The shortcomings of the short video platform, which mainly transmits information, in constructing a new field of knowledge learning are mainly the homogenization of content and the diversification of value. Parents, teachers and other adults should help minors to make good use of the knowledge resources of short video platforms, so that children can enjoy high-quality digital culture through entertaining. Short video is rich in content, diverse in forms, strong in story, short and pithy, and it is more convenient to "brush the screen" in free leisure time, so it has also become people’s leisure products. In order to better transform its entertainment into education and fully integrate entertainment and education, adults need to have high digital literacy.Give more practical help and guidance to minors.

  Parents and teachers should empower minors and create a digital environment suitable for their development. At the World Digital Education Conference held in February 2023, the Ministry of Education issued "Teachers’ Digital Literacy", requiring teachers to make good use of digital education resources to guide students’ learning. Similarly, parents also urgently need to improve their digital literacy, enhance their digital thinking, digital cognition and digital skills, and make good use of the digital cultural resources of the Internet platform with their children to develop a green and intelligent lifestyle. Parents and teachers should pay special attention to the following relationships in order to make children benefit from opening books to opening screens, and from simple entertainment to entertaining:

  Balance online life and offline life. The development of the Internet has increased the inclusiveness of knowledge and brought new learning experiences and knowledge acquisition channels to children. Parents and teachers should pay special attention to guiding children to balance online life and offline life. We should not only pay attention to enriching children’s online life, so that children can live a quality digital life, but also pay attention to children’s offline leisure, social, family life and campus life, so that children can have a healthy and positive offline life, which is more conducive to children’s online life and offline practice.

  Balance entertainment and education. Knowledge in the visual and interesting packaging of short videos makes children feel more interesting and easier to learn. However, in the eyes of many parents and teachers, they always feel "unlike" learning, because in the eyes of adults, they should "learn from the sea and work hard." As the children of the Internet aborigines, it seems that fun is the last word. Parents and teachers should pay attention to balance the relationship between the two, not only to meet the needs of the network generation for learning change, so that children can gain a sense of participation and belonging in their studies, but also to increase education in entertainment, so that children will not get lost in the network in joy, thus dispelling the "heavy feeling" of learning.

  Balance short and systematic. Shortness is both an advantage and a disadvantage of short video. Short knowledge is more convenient for students to watch and more suitable for children’s short attention time. However, learning knowledge also needs to be systematized, so as to avoid "the blind touch the elephant". Parents and teachers should make good use of their advantages, and at the same time, they should consciously guide their children to build the knowledge system they need, and conduct multi-dimensional and multi-level discussions around a certain topic and a certain kind of problems, so that children can overcome the problems brought by short video learning.

  Balance child practice and child protection. The barrage, comments and live broadcast of short videos are more interactive, which is also a "double-edged sword". The advantage is that children have more opportunities to participate, think and interact when learning online, but the problem is that it may also bring risks to minors. Therefore, we should not only encourage minors to participate in more practice, but also do a good job in protecting the rights and interests of minors. In particular, parents and teachers need to enhance their awareness of child protection, improve their digital literacy and that of minors, so that every child can enjoy the fun of knowledge learning.

Awesome, my C919! The first flight of China big plane is in sight.

  Wu Guanghui, chief designer of Comac C919 and ARJ21, has won the national special prize for scientific and technological progress and the first prize for national defense scientific and technological achievements. A key model won the first prize of China Aviation Industry Corporation I and the first prize of the National Defense Science, Technology and Industry Committee.

  "Many aircraft parts are made in China and fly in the sky every day. C919 has gone through nearly seven years, and has done a lot of design, calculation and experiments. I am definitely willing to take this plane first. "

  — — Wu Guanghui

  These days, in the commercial aircraft test center of China Commercial Aircraft Corporation, the newly-built Zhuqiao test hangar in Pudong is spacious and bright. In the hangar, the landing gear that originally supported the domestic large passenger plane C919 was all put into the landing gear cabin, and three air springs like "jacks" lifted the plane into mid-air. What is going on here is the ground resonance test and modal coupling test of the whole aircraft that must be completed before the first flight, which means that the C919 has officially entered the final sprint stage before the first flight.

  C919 is a domestic large passenger plane independently designed and developed by China. It is a short-haul single-aisle narrow-body passenger plane with more than 150 seats. In the future, it will compete with internationally renowned commercial aircraft such as Airbus 320 series and Boeing 737 series for orders. The manufacturer China Commercial Aircraft Co., Ltd. recently announced that the C919 plans to make its first flight in the first half of 2017 and will fully launch the wide-body passenger aircraft project. It can be said that after nearly 10 years of hard work, China people’s dream of "big plane" will soon become a reality.

  ① Rigorous test to ensure safety.

  To fly into the blue sky, a plane must first practice a pair of steel bars and iron bones. For the C919, which carries the dream of a big plane for Chinese people, the significance of the test is even more significant. This is the first large passenger plane made by China people, and its safety cannot be lost.

  For this reason, C919 has undergone a series of tests like "torture". Among them, the 2.5g static test of the whole aircraft started in early November last year is the most severe and significant one since the birth of the C919.

  This test mainly tests the strain and deformation of the "skeleton" of the body under constant external loading. In layman’s terms, this kind of test is to let the aircraft simulate the stress situation when challenging air flight on the ground, and go beyond the natural limit to verify how much force the aircraft can bear.

  Before the start of the experiment, the researchers covered the whole body with white adhesive tape, which is a resistance strain gauge that can sensitively measure stress and strain close to the surface of the body, just like doing electrocardiogram for the plane. During the test, the load starts to rise at the level of 5%, and the load must be kept for 3 seconds every time. "The structure must be able to withstand the ultimate load for 3 seconds without damage." Zhou Liang Dao, deputy chief designer of the C919 passenger plane, said that the preparation behind the team took more than 300 days for this short three seconds.

  With the continuous loading, the aircraft began to show obvious external reflection, and the wing began to tilt up a little. Finally, when the load reaches 100% of the test outline, the wing tip tilts up to nearly 2 meters, which is highly consistent with the strength analysis before the test, which shows that the test is successful and its strong "bones" and body are enough to support flying into the blue sky.

  This is just a small step in the long March before the first flight of the plane. A passenger plane has to complete 13 static tests in 48 working conditions, including pressurization in the booster cabin, front lifting connection, main lifting connection, whole aircraft condition, vertical tail and rudder, as well as "three-bird test" such as iron bird, copper bird and electric bird and joint test of the whole aircraft system. Therefore, researchers have made independent innovations in system integration experiments.

  In the comprehensive test hall of Shanghai Aircraft Design and Research Institute, the iron bird test-bed with little difference from the C919 real machine looks like an eagle with wings spread and its tail stuck high. Don’t underestimate this test-bed. Its full name is "Integrated Test-bed for Flight Control Hydraulic System", which mainly tests the landing gear, wings and other mechanical systems of aircraft. In order to ensure the authenticity of the system test, the iron bird test-bed is designed according to the 1:1 ratio of the real aircraft, so that the mechanical installation interfaces of the flight control, hydraulic and landing gear systems are the same as those of the aircraft.

  Next to the Iron Bird Test Bench, there is also a "Copper Bird" that tests power supply systems such as power generation and distribution, and also restores the real state of the machine to 1:1 for equipment installation. "Iron Bird", "Copper Bird" and the avionics system test called "Electric Bird" will eventually be all connected, thus forming a "three-bird joint test" to simulate the state of the aircraft.

  In the experiment, researchers conducted a comprehensive test on the aircraft system. Take the avionics system as an example. At most, there are more than 100,000 parameters in a test. These parameters should be tested one by one to find out the possible omissions in the design. "Our goal is not to take the fault to the sky." Yu Shenghui, senior engineer of the General Aerodynamics Department of Shanghai Aircraft Design and Research Institute, said.

  According to the plan, six testing machines are carrying out joint testing of the whole machine system, and customer service engineering and airworthiness work are also being carried out simultaneously.

  ②C919 is genuine China goods.

  As the first large passenger plane with completely independent intellectual property rights in China, C919 has been frequently questioned since it was established in 2006: an aircraft whose engine, avionics core processing system and some materials all depend on foreign products or technologies, why should it be said to be "made in China"?

  In fact, to evaluate the innovation of C919, we may need to draw lessons from a fairy tale named Pony Crossing the River. This story is about a pony crossing a river. A cow next to it said, "The water is very shallow, just without a calf, so you can cross it." But the squirrel in the tree said, "The water is deep and will drown." So, is the river deep or shallow? Finally, the pony got off the river by himself and carefully waded to the other side. It found that the river was neither as shallow as the cow said, nor as deep as the squirrel said. The same is true for the development and innovation of C919. Everyone should not only see the major innovations achieved in the process of aircraft development, but also objectively admit the existing shortcomings.

  According to international standards, judging whether an airplane is made in China or assembled depends on whether it meets three conditions. 1. Who owns the property right of the whole machine? Second, who is the core team to develop the whole machine? Third, who holds the key link in the development of the whole machine? For C919, the answer to these three questions is China.

  The person in charge of Comac in China said that the property right of the C919 is owned by Comac in China. The team of Comac in China is the core of the development, and the key links such as aircraft design, final assembly, test flight and sales are in the hands of Comac in China.

  As for foreign companies providing parts or technology, this is a common thing in the global aviation manufacturing industry. Aviation manufacturing giants such as Boeing and Airbus also use foreign products on many key components when developing aircraft.

  However, for equipment like engines, the C919 chose the LEAP-X1C engine jointly developed by the United States and France, which is the only foreign starting power device selected by the C919. It should be said that the engine is indeed a major constraint in the development of China’s large aircraft, and it can only be sought from people at present. However, I believe that in 10 to 15 years, China will be able to develop its own advanced aero-engine for large aircraft.

  ③ Have a number of scientific and technological innovations.

  Experts said that the C919 was completely designed and integrated independently, with outstanding technical indicators. It is the persistent innovation of researchers who have sharpened their swords for ten years that has led to the high-tech C919, which integrates many key technologies.

  However, what did C919 look like when it was approved as one of the 16 major projects in the national medium-and long-term science and technology planning in January 2006? What difficulties may be encountered in the development? Due to the limitation of western aviation powers in technology introduction, China researchers have no idea and can only cross the river by feeling the stones.

  In November 2008, the C919 project was launched. A large passenger aircraft joint engineering team composed of 468 experts from 47 domestic and foreign units, plus a large passenger aircraft expert consulting group composed of 20 academicians and experts, started from sketches and gradually sorted out the first batch of 14 special technical research projects that need to be started.

  Among these key technologies, there are several that must be mentioned. For example, the "supercritical airfoil" that makes airplanes more fuel efficient. A large passenger airliner is an out-and-out "oil tiger". In order to reduce fuel consumption, the wing design of C919 uses a supercritical airfoil, which improves the cruise aerodynamic efficiency by more than 20% and reduces drag by about 8%.

  Another unique innovation is the adoption of the third generation Al-Li alloy materials. It is the first time in China that the world’s advanced third-generation Al-Li alloy materials are widely used in the main structure of C919. Compared with ordinary aluminum alloy, this lightweight metal material with high damage resistance has greater strength and lighter weight under the same strength, which is very important to realize the weight reduction of aircraft structure and greatly improve the service life of aircraft.

  In addition, as the "brain" of the C919, the avionics system of the aircraft has realized "giving all the work to the network". Compared with the old version of the network, which was widely used before but had limited bandwidth, the new aviation bus communication protocol adopted by C919 not only has high bandwidth but also shares resources, which means that the signals that originally needed to be transmitted through several cables can now be transmitted by one cable. Experts said that this is like we need to run 10 trains from A to B, but we don’t need to build 10 railways. We only need a set of double-track railways and a reliable signal system.

  According to Wu Guanghui, the chief designer of C919, the developers have planned 102 key technical problems, and many advanced materials have been applied on a large scale in domestic civil aircraft for the first time. The development process of millions of parts and airborne systems is highly parallel. In order to overcome these technical difficulties, 22 provinces and cities, more than 200 enterprises, 36 universities and hundreds of thousands of industrial personnel participated in the development of C919 large passenger aircraft, and 16 material manufacturers and 54 standard parts manufacturers including Baosteel became suppliers or potential suppliers of large passenger aircraft projects.
