CCTV News:On June 24th, the 5th International Electric Vehicle Challenge around Qinghai Lake, jointly sponsored by Qinghai Provincial People’s Government, Ministry of Science and Technology, Ministry of Industry and Information Technology and China Electric Vehicle committee of 100, kicked off in Xining. The event specially arranged for drivers, sports stars to pray and stunt performances.

　　In this stunt show, professional drivers and his club drivers gave a uniform team stunt show at the beginning, performing fighter formation, word formation, wild goose wing formation, T formation and diamond formation. Since then, the drivers have carried out synchronous winding in the same direction, cross winding in the same direction, opposite winding and reversing winding respectively; Turn around 180 degrees in turn, turn around 180 degrees in turn, turn around 180 degrees in turn, turn around 180 degrees synchronously, turn around 180 degrees for a single car, turn around 180 degrees for a double car, turn around 180 degrees for a double car at high speed, turn around 180 degrees for a double car, and turn around 180 degrees for a double car. Speed face to face, multi-vehicle cross drift, 360-degree U-turn, 540-degree U-turn and other performances. Finally, the stunt drivers pushed the stunt show to a climax with the super difficulty of two-wheel driving around the pile and two-wheel driving jumping.

　　It is worth mentioning that this year’s electric vehicle challenge around Qinghai Lake coincided with the hot progress of the World Cup in Russia, and the organizing committee specially arranged the car shooting project in the stunt performance. Kui Yuanyuan, the world champion of gymnastics, Xue Ming, the world champion of women’s volleyball and Shi Jingnan, the world champion of short track speed skating, formed a star team, and personally drove the vehicle and had a wonderful and exciting shooting competition with professional drivers.

　　As the leader of the whole stunt performance, the captain of the "Challenger Car Stunt Club" has participated in the electric car challenge around Qinghai Lake for the third time. He talked about the stunt projects he did today, including drifting tail and two-wheeled driving, which are classic projects and also test the stability of the vehicle. When I participated in the electric vehicle challenge around Qinghai Lake for the first time, I was worried that the whole electric vehicle was not easy to operate, but it was very easy to get started in actual driving and the performance effect was also very good. Challenger Auto Stunt Club was established in 2012, and each team member has thousands of performances.

　　Looking at the whole stunt competition, it can be said that in the limited space performance venue, the strong acceleration performance of electric vehicles is fully displayed, which may not be achieved by the same-level oil-powered motor vehicles. Relatively heavy electric vehicles can make flexible and changeable drifting movements, which fully demonstrates the reliability of the electric vehicle chassis.

　　In addition, in the stunt performance of two-wheeled driving, the electric car with battery is heavier than the oil-powered car, but all the weight of the car is concentrated on two wheels, and it is not from the design stress angle of the original car, and the car is still intact when it falls down, which fully shows the reliability of the quality of the electric car.

　　In today’s performance, stunt drivers kept changing cars, so that almost all the participating cars appeared in the performance. Different brands of cars also have their own advantages. I believe that the real test will be ushered in the evaluation competition around the lake.

　　As ambassadors for public welfare promotion, the appearances of diving Olympic champion Sang Xue, gymnastics world champion Mo Huilan, gymnastics world champion Bi Wenjing, gymnastics world champion Kui Yuanyuan, women’s volleyball world champion Xue Ming, women’s volleyball world champion Ma Yunwen, taekwondo world champion Shi Jingnan, short track speed skating world champion Huang Jinxuan ignited the atmosphere at the event site.

　　When talking about new energy vehicles, Mo Huilan said that there is not much difference between electric vehicles and traditional vehicles in terms of driving experience, and electric vehicles have performed very well in mute, and more and more friends around them have begun to contact electric vehicles. The events around the lake have new highlights and growing influence every year.

　　As Shi Jingnan, who participated in the electric vehicle challenge around Qinghai Lake for the first time, this event made him pay more attention to environmental protection and convinced him that new energy is an inevitable trend of future development. With so many people working together, the future will definitely be better.

　　Sports stars said that they like electric vehicles very much, which is environmentally friendly and quiet. Holding such new energy events is not only of great significance to the evaluation and innovation of electric vehicle technology, but also helps to popularize the good social value of "green travel" and improve people’s awareness of green environmental protection. It is hoped that this event will promote the development of China’s new energy automobile industry and call on people to protect the natural environment.

　　The stars spoke highly of the electric vehicle challenge around Qinghai Lake (International) and were full of expectations for the next events.

　　Beijing, July 18 (Reporter Shangguan Yun) What if one day an asteroid hits the earth? This may be a scene imagined by many science fiction lovers. Earlier, it was reported that an asteroid might hit the earth on September 9 this year, but this possibility was finally ruled out.

　　On the 17th, "Asteroids will not hit the Earth in September" boarded a hot search in Weibo, which once again triggered a heated discussion: What is the "asteroid" we often talk about? What will happen if it collides with the earth?

　　The probability of "one in seven thousand" colliding with the earth

　　The hot search for "asteroids will not hit the earth in September" is related to an announcement issued by the European Space Agency on the 16th. According to media reports, the announcement pointed out that a mysterious asteroid discovered more than ten years ago was originally thought to have a small probability of hitting the earth on September 9 this year, but the latest observation data ruled out this possibility.

　　It is understood that this asteroid was discovered by astronomers in 2006, so it was code-named 2006 QV89. According to the observation data at that time, it had a probability of colliding with the earth on September 9 this year.

　　However, this asteroid was only observed in a short period of 10 days, and then mysteriously "disappeared". Astronomers never observed it again, which made it difficult to accurately calculate its current position.

　　Therefore, in order to judge whether the original observation results of QV89 "collision with the Earth" in 2006 are accurate, researchers have pondered a method: first, assume that the asteroid is still in the orbit that may collide with the Earth, and then observe its possible position in the sky on July 4 and 5, but found nothing.

　　Based on all kinds of data, this asteroid was finally considered to be no threat to the earth.

　　What the hell is an asteroid?

　　As the name implies, asteroids are celestial bodies in the solar system that move around the sun like planets, but their volume and mass are much smaller than those of planets.

　　"In 2006, scientists defined planets, asteroids and dwarf planets. For example, the earth is a planet, which basically lives alone, revolves around the sun, and has a relatively round shape. A typical dwarf planet is Ceres, and they are ‘ Live in groups ’ Yes, there are a bunch of celestial friends in the orbit. " Sun Zhengfan, a doctor of astrophysics and a popular science writer, said.

　　As for asteroids, compared with the first two, they are simply a group of strange little guys. Sun Zhengfan explained that asteroids also revolve around the sun, but they are not round in shape, and they are grotesque in shape, big and small.

　　According to public information, as of 2018, about 1.27 million asteroids have been discovered in the solar system, but due to the limitations of observation methods and other factors, this may be only a small part of all asteroids.

　　"If you search for near-earth asteroids or near-earth asteroids on the Internet, the number of them mentioned in relevant popular science articles will definitely surprise people." Sun Zhengfan said.

　　Asteroids and the mystery of dinosaur extinction

　　The powerful destructive power of asteroids hitting the earth can be known from scientists’ discussion on the mystery of dinosaur extinction. There is a well-known saying that an asteroid hit the earth about 66 million years ago was the direct cause of dinosaur extinction.

　　Specifically, this view holds that when an asteroid hit the earth, it triggered a huge tsunami, and the ocean on the surface of the earth suddenly rolled, but this was not the only disaster faced by dinosaurs.

　　The impact raised a lot of hot rocks and dust, which triggered a forest fire. Countless flying dust covered the sky, and the earth’s surface was not exposed to sunlight for many years. The global climate became cold and creatures became extinct on a large scale. Dinosaurs couldn’t adapt to the drastic climate change, and in addition, they were short of food and eventually went extinct.

　　"There are a pair of astronomers and their sons in the United States. In the strata around 66 million years ago, a metal element was found to have a very high content, but normally it has very little content in the rocks of the earth." Sun Zhengfan said, therefore, astronomers and their sons speculated that this metal element in the stratum exceeded the standard because an asteroid with a diameter of about 10 kilometers hit the earth at that time.

　　Of course, there are many different opinions about the reasons for the extinction of dinosaurs, such as volcanic eruption and so on. Sun Zhengfan introduced that some paleontologists believe that the extinction of dinosaurs is not a sudden event, but a process. Because of the long time, it is difficult to find a complete chain of evidence for many claims about the extinction of dinosaurs. The most popular one is "an asteroid hit the earth".

　　The disaster caused by "close contact"

　　In fact, people are worried about the "close contact" between asteroids and the earth because of the disaster and destructive power they may bring after hitting the earth.

　　For example, according to media reports, on February 15, 2013, an asteroid with a diameter of about 20 meters exploded over Chelyabinsk, Russia, which indirectly damaged more than 3,000 buildings and injured more than 1,600 people.

　　Astronomically, an object whose orbit is within 1.3 astronomical units from the sun (1 astronomical unit is the average distance between the sun and the earth, which is about 150 million kilometers) and whose orbit distance from the earth is less than 0.3 astronomical units is a near-earth object, which is a collection of near-earth asteroids and near-earth comets.

　　Among them, the potential impact with a diameter of more than 140 meters and the minimum distance from the earth orbit within 0.05 astronomical unit threatens celestial bodies and poses a direct threat to the earth.

　　"An asteroid with a larger diameter can easily cause serious disasters when it hits the earth." Sun Zhengfan explained that "asteroid impact on the earth" is a high-risk event, such as the impact that is thought to have led to the extinction of dinosaurs. There is still a huge crater in Mexico’s Yucatan Peninsula, half on land and half in the sea.

　　Asteroids are terrible? There is no need to be overly anxious.

　　Based on the possible serious consequences of an asteroid’s visit, the news that an asteroid may hit the earth often causes many people’s worries. But Sun Zhengfan said that there is no need to be too anxious about this.

　　"First of all, it can cause extremely serious consequences ‘ Asteroids hit the earth ’ It’s a small probability event, and secondly, our earth has the atmosphere ‘ Protector ’ 。” Sun Zhengfan said.

　　Data Map: The picture shows beijing aerospace control center’s real-time monitoring and control mission of "Chang ‘e II" flying over an asteroid on December 13th. Sun zifa

　　He explained that the earth is moving in space, and there are always a huge number of things falling on it, mostly in the form of dust, or just like pebbles, some asteroids burn out in the atmosphere. "There are no people in most parts of the earth, such as the sea and the desert. Therefore, it does not have much impact on human beings. "

　　Sun Zhengfan also admitted that with the current scientific and technological means, it is still difficult to accurately calculate the running paths of asteroids that may cause harm to the earth, and "we can only estimate their size and quality by reflecting light, and this data itself has errors".

　　"Preventing doomsday asteroids is a very important job." Sun Zhengfan said, "Humans can unite to develop aerospace technology and prevent this major disaster through early warning."

　　Tang Shanghai, 40, from Taihe Town, Hechuan District, bought a second-hand mobile phone in Daping, Yuzhong District. Unexpectedly, there was a yellow video in the phone. On September 18th this year, Tang Shanghai and his friend Chen Haijun went to Huaihua by train. A policeman turned on Tang’s mobile phone while checking tickets and found this pornographic video, so he fined 200 yuan for Tang Shanghai spreading obscene videos. Yesterday, Tang, who had just returned to Chongqing, told this newspaper that he did not spread obscene videos and refused to accept the fine imposed by Hangzhou Railway Police.

　　Police officers found obscene videos on mobile phones when checking tickets.

　　Yesterday morning, as soon as Tang Shanghai and his friend Chen Haijun returned to Chongqing from Huaihua, they introduced to reporters that Tang Shanghai was fined by a police officer on September 18th for storing a yellow video on his mobile phone.

　　According to reports, at 10: 30 am on September 18th, Tang Shanghai, who lives in Loufang Village, Taihe Town, Hechuan District, and his friend Chen Haijun took the K531 train from Chongqing to Hangzhou to Huaihua. At 1 o’clock in the morning on the 19 th, a policeman began to check tickets in the carriage.

　　"We took out tickets, wallets, mobile phones, etc. from our purses for him to check." Chen Haijun said that the policeman found that Tang Shanghai’s mobile phone was the same style as the one he used, so he opened it without authorization and skillfully checked various functions. Unexpectedly, the policeman found that there was a yellow video in the mobile phone. "Why do you have yellow videos on your mobile phone?" The policeman’s loud questioning made the surrounding male and female passengers stare at Tang Shanghai. "I was blushing and my neck was thick, and I felt ashamed." Tang said that he is over 40 years old, so he often watches obscene videos. He was afraid that passengers would think he was lewd.

　　Second, the mobile phone comes with porn, and the police call 500 yuan for punishment

　　Subsequently, the policeman ordered him to take his mobile phone and followed him to the restaurant carriage. After handling four or five fare evasion passengers, the police took him to an office. Tang said that he always explained to the police that he didn’t download the obscene video, but that when he bought a second-hand mobile phone, it had a yellow video of about 4 minutes on it, and he didn’t show it to anyone. However, the police still demanded a fine for 500 yuan on the grounds that Tang copied and disseminated obscene videos privately, and said: "You can do it without paying a fine. When you arrive at the next station, you will be handed over to the local station police station for administrative detention."

　　"I was scared when I heard it, and I quickly pleaded with him." Tang said that he begged for a long time, and finally the policeman still fined him 200 yuan and asked him to write down the inspection book on the spot.

　　Think that improper handling of passenger telephone complaints

　　At 2 o’clock in the morning on the 19th, Tang Shanghai and his friend Chen Haijun, who were more and more wrong, immediately complained to the police detachment of the Public Security Department of Hangzhou Railway Branch of Shanghai Railway Bureau that the police had not handled it properly. At about 6: 50 in the morning, Fang Instructor of the Police Detachment of the Public Security Department of Hangzhou Railway Branch of Shanghai Railway Bureau took the initiative to call Tang and Chen and explained that their police handling was legal and correct, but apologized to Tang Shanghai for the way and attitude of police handling.

　　Computer pornography was fined 1900 yuan.

　　On August 18th this year, three policemen from the network police detachment of Nanyang Public Security Bureau in Henan Province found two yellow videos in Ren Chaoqi’s computer. On September 12, Ren Chaoqi received a penalty decision from the police and was "warned and fined 1900 yuan". After the matter was reported by the media, it caused heated discussion among people from all walks of life. On September 26, Nanyang police announced the decision made by the Law Enforcement Supervision Committee of the branch directly under the Municipal Public Security Bureau: to revoke the fine imposed on Ren Chaoqi.

　　All parties’ statements

　　Passenger involved

　　Did not download and spread, refused to accept punishment

　　"The mobile phone is a second-hand mobile phone I bought in Daping. I bought this yellow video." Tang said that out of curiosity and boredom, he didn’t delete this yellow video, and only looked at it when he was bored. He said that he didn’t show it to anyone on the train. How can it be said that it is spread? Second, the mobile phone is his personal belongings, and the policeman should not have the right to check his mobile phone without permission. Tang Shanghai said that although the instructor of the police detachment of the Public Security Department of Hangzhou Railway Branch of Shanghai Railway Bureau took the initiative to call them and apologized for the way and attitude of the police, he thought that this was far from enough, and he simply refused to accept the punishment of Hangzhou Railway Police.

　　Hangzhou police

　　Fine 200 yuan appropriately.

　　Yesterday afternoon, according to the telephone number provided by Chen Haijun, the reporter contacted Fang Instructor of the Police Detachment of the Public Security Department of Hangzhou Railway Branch of Shanghai Railway Bureau. "I personally handled this matter." Fang said that after receiving the passengers’ feedback, they immediately asked the police on duty about the situation and then replied to the passengers, who expressed their understanding at that time.

　　"At that time, during the Olympic security period, the police had the right to check the passengers’ mobile phones." He said that Tang Shanghai copied and used computer information networks, telephones and other communication tools to spread obscene information, and it was appropriate for the police to fine 200 yuan according to Article 68 of the Law on Public Security Administration Punishment.

　　Chongqing police

　　Improper hasty fines imposed by police officers

　　The tax police officer in charge of the police detachment of Chongqing Public Security Department of Chengdu Railway Bureau said that it was very inappropriate for the police detachment of Hangzhou Railway Branch of Shanghai Railway Bureau to handle the police in such a hasty manner. He said that the police must first find out whether Tang Shanghai has spread obscene videos. If Tang Shanghai shows obscene videos in his mobile phone to the surrounding people and passengers, and spreads and sends obscene videos, the police officer has the right to check the mobile phone and impose a fine below 200 yuan.

　　The tax said that if Tang Shanghai said that he didn’t show it to anyone, and there was no evidence that he spread and sent obscene videos, it would be fine, which was inappropriate.

　　Chongqing lawyer

　　It’s not illegal to appreciate it yourself.

　　Zhang Jingzhu, a lawyer of Chongqing Esther Law Firm, said that obscene videos are stored in his mobile phone and are not spread, so it is not illegal to enjoy them occasionally. He said that Article 68 of the Law on Public Security Administration Punishment stipulates that only those who produce, transport, copy, sell or rent obscene books, periodicals, pictures, films, audio-visual products and other obscene articles or use computer information networks, telephones and other communication tools to spread obscene information will be dealt with. The communication mentioned in this regulation is, on the one hand, multi-person and large-area communication, and on the other hand, it is dangerous to society. Zhang said that Tang Shanghai did not have the conditions for transportation and communication, and the mobile phone was just a carrier.
