Mars probes in many countries have set a small goal for China to compete on Mars next year.

  CCTV News:There is such a planet, which lies between the earth and Jupiter and is the fourth closest planet to the sun. If you look at it with the naked eye, it will show a more prominent red color than the surrounding stars in the night sky of the earth. The ancients in China called it "as bright as fire". This star is Mars. Soon, we will have the opportunity to get in touch with it. On November 14th, the National Space Administration made public the Mars exploration mission in China for the first time, and planned to implement it in 2020.

  The mission of Mars exploration this time is the lander hovering obstacle avoidance test, which mainly simulates the process of lander hovering, obstacle avoidance and slow descent in the Mars environment at the ground test site, and comprehensively verifies the correctness of its design.

  The lander hovering obstacle avoidance test is the largest comprehensive test site for the landing of extraterrestrial objects in Asia. This test simulates the gravity environment of Mars, and the gravity acceleration on Mars is about one third of that of the Earth. According to the plan, China will launch the first Mars exploration mission next year. The goal is to realize the three tasks of "circling, landing and patrolling" through one launch mission, carry out global and comprehensive exploration of Mars, and conduct fine patrol exploration of key areas on the surface of Mars.

  Why launch next year? Only once every 26 months.

  Mars is not something we can go to if we want to. Do you know why we chose to launch in 2020?

  This is because there will be a "Mars Rush to the Sun" every 26 months. At that time, the sun, the earth and Mars will be in a straight line. At this point in time, Mars exploration will take the shortest flight route and save the most fuel. The closest window to the current time is 2020, so China’s Mars exploration mission is also aimed at this window.

  Moreover, not only China, but also the United States will launch "Mars 2020" next year, India will launch "Man Garian 2" next year, and UAE hopes to launch "Hope" &hellip next year; … Many Mars probes from all over the world have chosen to compete on Mars next year.

  Mars exploration "two steps" and one step to realize "round tour"

  Four hundred years ago, Kepler wrote in a letter to Galileo: "We should build ships and sails suitable for flying to the sacred sky, and then there will be such pioneers who will not shrink back in the face of boundless space." For the first Mars exploration, Chinese scientists have been working hard. Compared with other countries’ fire exploration missions in the past, China’s Mars has to complete the soft landing of the Mars probe at one time, which has a high starting point and is more difficult.

  Zhang Rong Bridge, chief designer of the first Mars exploration mission: put forward a two-step route. In the process of demonstration in 2013, one step will realize winding, landing and patrolling, and the other step will complete sampling and returning, so as to make our country reach the advanced level in the field of Mars exploration by 2030.

  Sun Zezhou, chief designer of the probe system for the first Mars exploration mission: For some time, the implementation of the lunar exploration project has been a technical traction. In terms of technical ability and technical level, we have the technical ability and technical level to realize the circumnavigation, landing and inspection at one time.

  Sun Zezhou said that based on the technology in the lunar exploration project, China has carried out pre-research on the key technologies of Mars exploration. The research and development of many new technologies needed for the characteristics of Mars exploration is also progressing steadily. For example, the parachute used to land on Mars is a breakthrough technology development.

  Sun Zezhou, chief designer of the probe system for the first Mars exploration mission: Our earth’s parachute is opened at subsonic speed, and the Mars probe is to open at supersonic speed. In this way, under a complicated aerodynamic condition, the design of the umbrella still needs a lot of work for us before we can really master it.

  Why do we need to explore Mars when the road is too long?

  Going to Mars is really not that easy. Apart from the window period and technical difficulties, there is also the problem of time. It takes about 6 months to sail just to go, and with the processes of sampling and returning, it takes about 3 years for a complete round trip. Since it is so difficult, why should we explore Mars?

  A year on Mars is 687 Earth Days, and a Mars Day is almost as long as Earth Day. There are also four seasons here, spring, summer, autumn and winter. Its diameter is half of the earth’s, its weight is one tenth of the earth’s, and its gravity is one third of the earth’s. The weightlessness is not too serious. You can still keep your feet on the ground and look up at the stars when you board Mars. It’s a little cold on Mars, with an average temperature of minus 55 degrees Celsius, reaching minus 100 degrees Celsius in the coldest night, and 20 degrees Celsius in the equatorial region at noon in summer, which is very comfortable. In addition, humans have discovered underground salt lakes on Mars.

  At present, humans have conducted more than 230 solar system explorations. The detection result shows that among the eight planets, five dwarf planets and 165 satellites in the entire solar system, only Mars is the most similar to the Earth, and only Mars may be transformed to realize large-scale immigration. So far, we can’t find a second such planet in the universe.

  What should I do to explore Mars this time?

  So what are we going to do this time to explore Mars?

  Experts say that the primary scientific problem of Mars exploration is to detect the information of life activities on Mars, including whether there was life on Mars in the past, the conditions and environment for the existence of life on Mars, as well as the origin of life and the exploration of extraterrestrial life. The second is to accumulate information for the scientific research of Mars ontology; The third is to explore the long-term transformation of Mars and the prospect of establishing a second habitat for human beings in the future.

  Maybe in the next twenty years or so, we can see that humans will land on Mars for the first time. In the next hundred years, we may build a medium-sized Mars city on Mars. In the next thousand years, we may transform Mars into a planet suitable for human habitation.

Physics college-ma yuncong

On February 3rd, Ma Yuncong, a student from the School of Physics of Jilin University, took the initiative to sign up and contribute to the fight against the epidemic when he learned that volunteers were needed at the epidemic prevention and control detection card point in Runanbu Town, Zhengyang County, Henan Province. During his duty, Ma Yuncong helped the doctors, public security police, residents’ committee staff to do propaganda, persuasion, registration, disinfection and so on. Later, under the recommendation of the Party branch of the neighborhood Committee, he also served as the red agent of Jinji neighborhood Committee, responsible for helping families in need, buying daily necessities and delivering them on their behalf, so as to reduce unnecessary travel.

"During this period of volunteer service, I feel that the party and the government attach great importance to this epidemic. People from all walks of life donated to the testing point, which made me feel the concern from everyone and have a sense of responsibility to do a good job. Life is more important than Mount Tai, epidemic situation is the command, and prevention and control is the responsibility. At the critical juncture of fighting the epidemic throughout the country, as a student of Jilin University and an activist joining the Party, I feel extremely proud and proud to make my own contribution to the prevention and control of our town and the country’s anti-epidemic. " He said.

Zhang Yan, College of Food Science and Engineering

Zhang Yan is an undergraduate from the College of Food Science and Engineering of Jilin University in 2016. With the call of the county youth league Committee and the support of her parents, she became a member of the "Volunteer Red". "This is the responsibility of a young college student, and it is also the responsibility of preparing for party member." Zhang Yan said.

During several days of community persuasion, she and her friends, who are also from Jilin University, actively checked the foreign population and vehicles, checked their body temperature, registered the information of people coming and going, told them about travel precautions, publicized the knowledge about epidemic prevention and control, and distributed booklets of novel coronavirus legal knowledge. Outdoor volunteer work may have frozen her bare wrist, but a mask, a red vest and the afterglow of the sunset made Zhang Yan feel particularly warm this winter.

Kindergarten learning content reaches the level of grade 2! Officially carry out special governance.

  The Municipal Education Commission and the Education Supervision Office of the municipal government will carry out special treatment on the "primary school" of kindergartens. Before the end of March next year, kindergartens, primary schools and educational institutions with problems will be comprehensively rectified. Beijing Youth Daily reporters visited some private kindergartens as parents, and found that it is normal to set up "after-school delayed classes", "pre-school classes" and "young connecting classes" in kindergartens. Adding and subtracting, recognizing seven or eight hundred Chinese characters within 100, reciting Disciples Rules, learning "logical rules" and other foreign primary school contents are all in the learning list, and the learning difficulty reaches the level of the second grade of primary school.

  policy

  The city started the special treatment of kindergarten "primary school"

  In July this year, the General Office of the Ministry of Education issued "On the development of kindergartens ‘ Primary school ’ Notice of Special Governance Work "clarifies five major governance tasks: it is strictly forbidden to teach primary school curriculum content; Correct the "primary school" education mode; Rectify the "primary school" educational environment; Solve the problem of unqualified teachers’ qualifications; Primary schools should adhere to zero-starting teaching. A few days ago, the Municipal Education Commission and the Education Supervision Office of the Municipal People’s Government announced the "Notice on Carrying out the Special Governance Work of" Primary School ".The notice emphasized that measures such as combining self-examination with mopping, combining spot check with rectification, and combining centralized rectification with long-term mechanism will be taken to comprehensively consider and gradually promote the implementation of games as the basic activity in kindergartens, strictly implement the" zero starting point "teaching in primary schools, and strive to standardize the educational behavior of education and training institutions.

  According to the requirements, the self-examination and arrangement will be completed before the end of October this year. The district education committees will formulate their own governance plans, organize kindergartens, primary schools and education and training institutions to carry out self-examination as required, and the district education committees will carry out spot checks and arrangement, make corrections while checking, and resolutely correct all kinds of wrong behaviors that tend to be "primary school". Before the end of March next year, the Municipal Education Commission will carry out spot checks and investigations on the special treatment of "primary school" in kindergartens, promote rectification, and rectify kindergartens, primary schools and education and training institutions with major problems according to laws and regulations.

  Private kindergarten "young connecting class" has become an enrollment gimmick

  The director of a public kindergarten told the reporter of Beiqing Daily that in his kindergarten, he mainly emphasized the cultivation of children’s habits and learning ability, and emphasized the combination of conservation. Let children increase their knowledge of things through various games and activities. "For example, we will take the children in large classes to visit the primary school to let them know what the primary school is like, what the bathroom is like, how to study, etc., and we will never give the children classes in advance, let them recite ancient poems, leave homework after school, etc."

  The reporter of Beiqing Daily learned that it is precisely because the training program of public kindergartens does not involve specific primary school textbook knowledge that it has become a gimmick for private kindergartens to attract students. "If you are in kindergarten in Tongzhou, we want to go to primary school in the city in the future. Preschool classes must be attended. If you don’t learn anything, you can’t keep up with the progress of primary school learning. If you don’t learn anything, you will definitely suffer. " Ms. Liu, a kindergarten supporting a community in Tongzhou, revealed to the reporter of Beiqing Daily. "Pinyin is very difficult to learn. The primary school teacher soon taught it, and it is not easy to master it. After the big class, we have a special Pinyin teacher to delay the children after class. In the past, our own kindergarten taught Pinyin in the big class, but now we are not allowed to teach it. We will take it out as a delay after class." The staff of a private kindergarten in Xicheng District also introduced to the reporter of Beiqing Daily.

  parent of a child

  "Learning is simple, what should I do after going to primary school?"

  The reporter of Beiqing Daily learned from some parents that although private parks are constantly "ahead" of their children’s learning content, parents always respect it. "In fact, these contents in preschool classes in kindergartens are not difficult, and I think they are too simple." Jia’s parents said that in addition to attending preschool classes in kindergarten, she also reported her Erbao to the preschool classes of off-campus training institutions, which made her learn more advanced. In mathematics, she had to learn acute angles, right angles and obtuse angles, and she had to learn rays and line segments. "There are also questions like this, how long a snail climbs a tree, how much it climbs the first day, how much it climbs the next day, and then ask how much it can climb in a few days &hellip. …”

  "To tell the truth, these children are really struggling to learn before they go to primary school, and they don’t quite understand. But I also learned lessons. My first child didn’t learn so much before, so I fell behind. " The parents said that the reason why children learn so advanced in kindergarten is that parents have no choice. "Like public kindergartens, they don’t teach anything, and they learn simply. What should we do after going to primary school?" Some key primary schools have to interview in advance, and interviews are very difficult. "

  survey

  Difficult content

  The content of kindergarten graduation study reaches the level of the second grade of primary school.

  The reporter of Beiqing Daily learned from the parents of some children attending private kindergartens that the difficulty of children’s learning in kindergartens at present makes parents feel "difficult". Can add and subtract within 100, and can recognize 700 or 800 Chinese characters … … For Jia’s parents who send their two children from private kindergartens to primary schools, these are all "one-stop services" that kindergartens have to do before primary schools, that is, after finishing small classes, middle classes and large classes, they have to attend kindergarten preschool classes for half a year to one year. The content of the preschool class is the content of the primary school. "Four English classes a week, three foreign teachers, one Chinese teacher and one Cambridge student".

  The parents of the children in the middle class of another private international kindergarten in Beijing also revealed to the reporter of Beiqing Daily that every Tuesday, the kindergarten has a half-day Chinese class to teach Chinese studies. One of the contents is to recite Disciples Rules from beginning to end … … "Because private kindergartens use textbooks independently selected by the park, parents can’t judge whether the content they learn is age-appropriate and conforms to the children’s cognitive laws, but it is obviously beyond the scope to recite the Disciple’s Rules in full text, even not the requirements of primary school students. This is really too difficult, but kindergartens require memorization and can only do it." The parent mentioned.

  When it comes to mathematics, the parent also said that in addition to Chinese classes, the content of mathematics classes in the kindergarten is also a difficult IQ problem, and even involves the problems of series and logical laws. "Like finding laws in ABAB, AABB and 234234. Mathematics is mostly similar to this kind of IQ test, which requires improving children’s ability to recognize laws. " The parents also revealed that because the children are attending international classes in kindergartens, they are taught by foreign teachers for one and a half days every day, and half of them are in an English environment. Therefore, the English teaching level of children from the age of five has already exceeded the normal teaching scope of primary schools today. "English has to be learned early, but the situation of each child is different. My small class can still keep up, and the middle class is a bit difficult."

  The reporter of Beiqing Daily learned from an on-the-job teacher of a public primary school that the level of adding and subtracting, recognizing seven or eight hundred Chinese characters, memorizing the complete Disciple Rules and the "logical law" of mathematics within 100 years of kindergarten graduation has reached the level of the second grade of primary school.

  Heavy burden

  Parents have homework every day and have a "mid-term" exam.

  As parents, the reporter of Beiqing Daily called and visited some private kindergartens in Haidian District, Tongzhou District and Xicheng District respectively, and found that some private kindergartens set up courses in the name of "young connection" and "preschool class". When the reporter of Beiqing Daily visited a supporting kindergarten in Tongzhou District, he found that in addition to the regular classes such as small class, middle class and large class, the kindergarten also has preschool classes. I saw rows of desks neatly arranged in the classroom of preschool class, and the curriculum plan of preschool class was posted at the door of the classroom. The reporter of Beiqing Daily noticed that the study contents in the first week of September in the course plan included learning the correct pronunciation and four tones of vowels A, O and E, knowing the four lines and three grids, and practicing the correct possessive writing. The mathematical contents include knowing the adjacent number, knowing that two numbers with a difference of 1 are adjacent to each other, and correctly judging the adjacent number … …

  The reporter of Beiqing Daily also learned that in this preschool class, the curriculum is similar to that of primary school. Chinese, mathematics and English are taught in different subjects, and there is morning reading in the morning. There are special textbooks, and Chinese characters, pinyin and mathematics are all studied, and every day the teacher will assign homework. "Teachers send homework to parents through parents, and we have exams every six months, which is equivalent to giving children a summary of one semester and also to let children develop the habit of being in school." The person in charge of Liu in the park introduced to the reporter of Beiqing Daily.

  High fees

  Young convergence embedded in the large class course charges 1980 yuan per subject.

  The reporter of Beiqing Daily learned that most young bridging courses will be embedded in the courses of large classes. The person in charge of a supporting kindergarten in a community in Tongzhou told the reporter of Beiqing Daily that if your child starts to attend a small class at the age of 2 and a half, it can last for four years, and then go directly to preschool after the big class. If you plan to have a small class when your child is 3 years old, you can go directly to preschool after the middle class. "The charging standard is the same as the normal large class and small class in the park, with a monthly fee of 4,350 yuan. Our preschool class uses the professional courses of the organization, which is very professional. " The person in charge of Liu said.

  The reporter of Beiqing Daily also learned from a private kindergarten in Xicheng District that the kindergarten has after-school delayed classes from small classes to large classes, including abacus, pinyin, painting, robotics and other courses, which are voluntarily registered by students. Large classes include abacus mental arithmetic and pinyin.

  The reporter of Beiqing Daily found that after-school delayed classes of English subjects can be attended from small classes. "We mainly serve parents. Some parents can’t pick up their children after work, so they use this 5: 00 to 6: 00 to open some extra-curricular delayed courses. The fees are much cheaper than outside. For example, English is held twice a week, and each semester is only 1980 yuan, from small classes to large classes."

  Premature indoctrination of super-class content is not good for children’s body and mind

  Chu Zhaohui, a researcher at the Chinese Academy of Educational Sciences, said: Kindergarten itself should let children grow up through games, and it is a relatively independent learning segment. Premature exposure to standardized knowledge has a great influence on children’s development. Chu Zhaohui said that when children who learn knowledge in kindergarten enter the first grade, their test scores are higher than those of children who play games in kindergarten. However, in the second and third grades, it began to divide, and many children’s academic performance declined in the third grade, which we called "the third grade phenomenon".

  Studies have shown that the younger a child is, the shorter his concentration time will be: 9 minutes at age 3, 12 minutes at age 4 and 14 minutes at age 5. The "primary school" of early childhood education is a repetitive education. If children are forced to concentrate for a long time, it will be harmful to their physical and mental development and not helpful to instill the learning content beyond the outline too early.

Is allergen testing "futile", or can it really find out the "culprit" of sensitization?

  Allergy survey ②

  Generally speaking, the results of allergen detection combined with medical history are relatively reliable. Allergic people don’t need to do allergen testing regularly, just wait until they have allergic symptoms but are not sure about allergens. In addition, they should choose professional and qualified institutions for testing.

  Is allergen testing reliable?

  This is one of the most frequently asked questions by Hu Liang, a pediatrician in Changchun Children’s Hospital. Many people suffer from allergies. In order to find allergens, they went to the hospital for allergen testing, and found that they were "lonely". The test results did not seem to be very helpful to control allergies.

  So, what are the main methods of allergen detection? How effective are these methods? Why do some people feel that they have "tested in vain"? Around these problems, the reporter of Science and Technology Daily interviewed relevant experts.

  Identifying allergens is the key to controlling allergies.

  Allergic diseases are also called allergic diseases, commonly known as allergies. According to the data, it is estimated that by 2050, about 4 billion people in the world will suffer from allergic asthma, allergic rhinitis and atopic dermatitis, and allergy has become the sixth largest chronic disease in the world.

  Allergy is closely related to allergens.

  Jiang Weihong, chief physician of the Department of Otolaryngology, Head and Neck Surgery, Xiangya Hospital, Central South University, said that allergens enter the human body through oral administration, inhalation, contact or injection, and bites, and allergic reactions occur in the human body. Therefore, if you want to control allergies, the key is to diagnose and determine allergens. Only by clarifying the cause of allergy can we correctly choose the treatment plan.

  However, there are many kinds of allergens in life, the most common are food allergens and inhalation allergens, and some are contact allergies.

  So, how can we "find out" the allergens that really cause allergies? This requires allergen testing.

  Liu Yongsheng, director of dermatology department of Aviation General Hospital, said that patients with allergies will produce specific IgE in their bodies after being exposed to allergens, and then the specific IgE will enter the circulatory system and be transported to all parts of the body, where it will combine with mast cells and basophils. Mast cells and basophils combined with specific IgE will meet and combine with allergens again, and then trigger mast cells and basophils to release inflammatory factors, such as histamine, which can directly lead to allergic inflammation and cause symptoms of type I allergic reaction in human body.

  "So, what is usually called allergen testing is specific IgE." Liu Yongsheng said.

  Different detection methods have their own advantages and disadvantages.

  Liu Yongsheng introduced that the methods of allergen examination can be roughly divided into intradermal test or prick test, serum test, patch test and provocation test.

  The principle of intradermal test or prick test is to let a certain amount of allergens enter the skin through a specific way, and then observe whether the allergens will cause allergic reactions, and judge the degree of allergies according to the degree of local skin allergic reactions, which is commonly known as "prick test". Liu Yongsheng said that this method has the advantages of simplicity, convenience and intuitive results, and patients will not wait too long for examination results.

  If intradermal test or prick test is an indirect method to determine specific IgE in vivo, then blood test is a means to directly determine specific IgE in serum.

  Shi Haiyun, chief physician of the Department of Allergy, Beijing Shijitan Hospital affiliated to Capital Medical University, said that if patients are unable or unwilling to adopt intradermal test or prick test for various reasons, they can choose to directly determine the specific IgE in serum. If specific IgE can be detected and reaches a certain value, it can be preliminarily judged to be allergic. By measuring the content of specific IgE in the body, such as serum, the degree of allergy can be preliminarily judged. However, serum examination requires special equipment and high cost, and the patient needs to wait for several days or more for the examination results. In addition, at present, the types of allergens that can be detected by serum testing are limited.

  If contact allergens are detected, patch test can be used, and when allergens are unknown, patch test can also be done. The operation method of patch test is to stick the reagent on the skin, and after observing for a period of time, judge whether the subject is allergic to the substance according to the skin’s reaction to the contact substance.

  Liu Yongsheng added that another way to check allergens is provocation test, such as oral food provocation test, nasal mucosa provocation test, conjunctival provocation test and bronchial provocation test. The principle of these tests is to simulate a real allergic reaction, which has certain risks and is not often used in clinic.

  Shi Haiyun said that allergen detection methods have their own advantages and disadvantages, and which allergen detection method to adopt should follow the doctor’s advice.

  Liu Yongsheng said that after the allergen test, the doctor should make a comprehensive judgment according to the patient’s medical history to determine whether he is allergic. "In addition, patients should pay attention to observing and recording substances that may cause allergies in order to find and avoid corresponding allergens."

  Allergen detection may have some blind spots.

  Although the methods and techniques of allergen detection are relatively complete now, there are also cases in which allergens cannot be detected or allergens are misjudged in clinic. In this regard, Liu Yongsheng explained that due to many factors, to some extent, there are some blind spots in allergen testing.

  Some blind spots are related to allergen detection methods. Taking the prick test as an example, patients with skin scratches may have false positive results. That is to say, some people were not allergic originally, and the allergen itself did not cause allergic reaction in patients, but acupuncture operation caused skin redness, swelling, itching and other reactions, which made inspectors mistakenly think that patients had allergic reaction.

  Some blind spots are caused by external factors. For example, heating is one of the commonly used ways in food processing, and when food allergens are detected by immunological methods, heating will lead to changes in the structure of protein (allergen), so that antibodies cannot correctly identify the detected allergens, resulting in false negative results. For another example, ELISA is one of the commonly used methods to detect allergen wheat, but it is easy to cause false negative or false positive results because the samples are easily cross-contaminated.

  Liu Yongsheng introduced that some blind spots of allergen detection are related to the complexity of allergen itself. There are about five or six hundred kinds of external allergens, and traditional methods can only screen 10 to 30 items, which is not comprehensive. Moreover, allergen detection is a meticulous work. For example, milk is one of the eight major allergic foods, and there are more than 30 kinds of allergic protein in milk. To determine which protein is allergic, more sophisticated detection means are needed. "Some people are allergic to cats, but whether they are allergic to cat hair, cat dander, cat saliva or cat urine, it is not clear from an allergen test." Liu Yongsheng said.

  It is worth noting that some allergic patients take anti-allergic drugs before testing allergens, which will also cause false negative test results. Experts suggest that if the intradermal test is chosen to detect allergens, patients should stop taking antiallergic drugs for about 7 days, and some drugs need to stop taking them for a longer time.

  "In addition, the relevant technologies and equipment for allergen testing and the level of doctors who test allergens for patients may also affect the results of allergen testing." Liu Yongsheng added.

  "In order to accurately lock allergens, not only excellent technical means are needed, but also doctors need to patiently ask about medical history. Combining allergen detection methods and medical history to judge allergens, generally speaking, the results are relatively reliable. " Liu Yongsheng suggested that allergic people don’t need to do allergen testing regularly, but only when they have allergic symptoms but are not sure about allergens. In addition, they should choose professional and qualified institutions for testing.

Inception issued a Chinese poster starring in the dream street

  Inception will enter the mainland screen on September 2nd, and the world-renowned director Christopher Nolan will surely arouse the brains of mainland audiences again with this "contemporary sci-fi film happening in the ideological structure", and people will also see Leonardo DiCaprio’s heroic spirit on the big screen for the second time. This time, Inception released the Chinese version of the poster, only to see Leonardo DiCaprio, Ken Watanabe, Joseph Gordon-Levitt, ellen page and other leading actors standing on the street with serious expressions, and the background was an overturned dream city, which was as fantastic as a dream, full of unknown mystery and tense and solemn atmosphere, making people marvel at the mystery and power of the "dream machine". Along with the Chinese version of the poster, there is the first official Chinese version of the trailer in Inception.

"The Dark Knight" director’s masterpiece stars gather together and big names gather.

  Inception is Christopher Nolan’s latest masterpiece after The Night Knight. In the world described in this film, human beings have invented a means to enter other people’s dreams. The story scene is not only set in many real-life areas around the world, but also extended to private dreams that give people unlimited imagination. Inception’s cast is quite strong, and Leonardo DiCaprio plays Cobb, the "Inception Man", who is the soul of the team; Joseph Gordon Levitt, who became popular with 500 Days with Summer, plays Arthur, Cobb’s assistant, and he will dedicate most of the funny scenes in the film. "Juno" ellen page plays a female college student named Aaliyah Deni, who is Leonardo’s partner in the play; Japanese actor Ken Watanabe plays the villain Qi Teng, and he will blackmail Leonardo.

Inception’s momentum is like a rainbow, and the global box office is nearly 500 million

  Since its release, Christopher Nolan’s summer masterpiece, Inception, has won many box office titles with an avalanche. After the film was released in North America, the box office went red all the way, breaking through 100 million dollars in the first week, and then it stayed at the top of the North American box office for three weeks. By the end of last week, Inception had won 230 million North American box office. In contrast to the North American box office of this film, Inception’s overseas performance is also excellent, not only in France, Spain and other places, but also in Britain, South Korea, Germany, Australia and other places. At present, the total overseas box office of this film has reached 250 million. I believe that with the release of more countries and regions and the mainland on September 2nd, Inception will make even greater breakthroughs.

How can the hydropower that "depends on the weather" be "guaranteed by drought and flood"? Clean energy helps to meet the peak summer.

CCTV News:Now it is the preparation stage for the peak summer. The National Energy Administration predicts that the national maximum power load will increase greatly this year compared with last year. In Sichuan, hydropower accounts for 80% of the local total power generation. Last summer, there was a "double shortage" of electricity and electricity because of the minimum rainfall in the same period in history. How is the preparation here during the peak electricity consumption this summer?

Yalong River Basin, which is rich in hydropower, is the third largest hydropower base in China. There are seven hydropower stations in operation along the Yangtze River, including Ertan, Jinping and Lianghekou. The reporter found in the Yalong River basin that the hydropower stations here are actively lowering the water level. According to the person in charge of the power plant, hydroelectric power generation has the characteristics of depending on the weather. For the purpose of flood control and storage regulation, large-scale reservoir power stations will reduce the water level before the rainy season, free up the storage capacity, and store the excess water in the rainy season for power generation in the dry season.

The effect of self-regulation of a single hydropower station is actually limited. At Lianghekou Hydropower Station, the most upstream of the seven hydropower stations in Yalong River, the reporter saw a large reservoir. Its total storage capacity is 10.8 billion cubic meters, which is equivalent to about 770 West Lakes. This kind of reservoir, which can regulate hydropower stations in the whole basin, is called "leading reservoir".

Besides water energy, the Yalong River basin is also rich in light energy. Cora Photovoltaic Power Station, located at an altitude of 4,600 meters, will be completed and put into operation in June, with an installed capacity of 1 million kilowatts in the first phase and an average annual power generation of 2 billion kWh. It is the largest water-light complementary power station with the highest altitude in the world.

Yang Zhiwei, Project Manager of Cora Photovoltaic Power Station:Photovoltaic light resources (on the plateau) are abundant in winter and weak in summer, so photovoltaic power generation is relatively large in winter, while hydropower is just the opposite.

In dry season, photovoltaic power generation is more, and hydropower power generation is less; In the wet season, photovoltaic power generation is less and hydropower power generation is more. The electricity generated by Cora photovoltaic power station will not be directly connected to the power grid, but connected to the hydropower station first, tied together with the electricity generated by the hydropower station, and then connected to the power grid.

Chen Feixiang, Deputy Director of Lianghekou Power Plant:The output of photovoltaic is a zigzag unstable curve. After water and light complement each other, the sawtooth random fluctuation of photovoltaic becomes a stable or even a straight line stable output, which makes our power more stable.

Wu Bing, Deputy Director of Electric Power Department of National Energy Administration:The integrated development and construction of water, scenery and scenery in major river basins will help to achieve the goal of double carbon and improve the level of energy security.

The reporter learned that during the critical period of peak summer, the supply capacity of cascade hydropower stations in Yalong River in Sichuan is expected to be 49.4 billion kWh, an increase of 2.3 billion kWh compared with last year.

Guarding their homes, they rushed to the front line of fighting floods.

  In the early morning of July 28th, Zheng Jichun set out with a small boat. His destination is the collection point of living materials in the town. Since 82 affected people in the village came to the resettlement site, as the principal of Gaolin Primary School in Sanbing Town, Chaohu City, Anhui Province, Zheng Jichun, an old party member, volunteered to take charge of everyone’s daily life. "The public sentiment is urgent. I have not been able to fight floods in the front line like other party member, but I hope to do my best to help the affected people eat and drink at the temporary resettlement sites." Zheng Jichun said.

  Since the flood season, there has been continuous heavy rainfall in Hefei, and all the main rivers in Chaohu Lake basin have exceeded the police. At the same time, they are under great pressure from the flood control of the Yangtze River and Chaohu Lake and the urban flood control. In the face of severe flood, Party organizations at all levels in the city and many party member bravely took the lead and rushed to the key positions of flood control, building dams for flood control and flood fighting, guarding their homes and the safety of people’s lives and property.

  Keep safe and branch to the front line.

  21 temporary party branches are on duty 24 hours a day, guarding major rivers, Chaohu dams and key areas.

  The water level in Chaohu Lake has exceeded the once-in-a-century standard for many days.

  There are three rivers entering the lake and 10.8km Chaohu levee outside. Yicheng Street in Baohe District of Hefei City is in the front line of flood control. In order to carry out flood control and emergency rescue work in a timely and effective manner, the Party Working Committee of Yicheng Street set up a temporary party branch immediately after receiving the flood warning, and moved 17 party branches of government agencies, residential villages and urban management to the levee.

  The temporary party branches are in charge of each section, with the branch secretary taking the lead and party member participating in it. The surrounding people saw it and took the initiative to join it. In a short time, more than 300 volunteers gathered, including more than 200 party member.

  "The water level is rising!" When patrolling the embankment, Yang Guoqing observed that the water level in Lirong section of the road around the lake was rising, and the embankment nearly 10 meters long in front was low in terrain, which was in danger of overflowing at any time. As the leader of a flood control emergency group, Yang Guoqing made a decisive decision and quickly organized to reinforce the dam. Shovel silt, tie bags, pass sandbags and build dams. Yang Guoqing and more than 10 party member fought together for nearly 2 hours, raising the dam by 1.2 meters.

  On the flood control dam, besides party member volunteers, there are fishermen "soil experts". Shu Congming, 68, is a native of Chaohu Lake and an old party member. He took the lead in setting up an "old fisherman’s dam guard team". The team members not only patrol the dam during the flood season, but also clean up the weeds and garbage along the lake and river on weekdays. Now, under the leadership of Shu Congming, this "old fisherman’s dam guard team" is divided into two roads, patrolling the embankment once an hour and being on duty 24 hours a day.

  "In front of the flood, a grassroots party organization is a fighting fortress." Ge Rui, secretary of the Baohe District Party Committee of Hefei City, said that building a temporary party organization in the front line of flood control and disaster relief can transform the party’s political advantages, organizational advantages and close ties with the masses into a powerful synergy for flood control and disaster relief. Today, Baohe District has set up 32 flood control emergency duty points and 21 temporary party branches in major rivers and Chaohu dams and key sections, and implemented 24-hour lighting duty.

  Patrol the dam, party member rushed ahead.

  At present, more than 50,000 party member cadres have devoted themselves to flood control and emergency rescue.

  At 6 o’clock in the morning, at first light, Li Yebing got on the electric motorcycle and rushed to the dam. When he reached the Nanfei River, he put on his raincoat, rubber shoes and shovel, and began to patrol the embankment. Party member, a 72-year-old man from Shikou Community, Changlinhe Town, Feidong County, Hefei City, has been involved in flood control since late June. "I am old, but I have much experience! It is glorious that I can still play a little residual heat before the flood. " Li Yebing introduced with a smile that there are eight people involved in his community, each of whom is responsible for inspecting the dam about 1.5 kilometers. "At first, it was a six-hour patrol, and later it became three hours. Now, it is necessary to patrol the embankment every hour."

  It’s still raining, and the water level of Nanfeihe River is rising almost every day. Li Yebing patrolled the embankment and dared not slack off. At noon, I got a box lunch and sat on a pony. While eating, Li Yebing still kept an eye on the water. "Once it is found that the water level exceeds the safety limit or leaks, it must be rushed up at the first time. This is my responsibility as an old party member! Don’t say that I am only 72 years old. Even if I am 82 or 92 years old, I will still stick to the front line of flood control. " Li Yebing said.

  "The flood fighting and emergency rescue is a big test for party member. They move at the command and smell ‘ Flood season ’ Attacking, regardless of gains and losses, fighting selflessly, fully embodies the responsibility and responsibility of Communist party member. " Yao Fei, county magistrate of Feidong County, said.

  It is understood that at present, more than 50,000 party member cadres have been involved in flood control emergency rescue in Hefei, and more than 380 party member commandos, more than 260 party member rescue teams and more than 650 party member volunteer service teams have been established.

  Anti-waterlogging, no dead angle in investigation

  Knocking on the door from door to door, earnestly persuading them to leave, working for dozens of hours, and moving the pump truck to help drain nearly 420,000 cubic meters of water.

  Not long ago, heavy rain poured down in Hefei. "No, there is water at the intersection of North First Ring Road and Feixi Road!" In Hefei Urban and Rural Flood Control Headquarters, he hung up the phone, and Chen Shiyong immediately called up the flood control command and dispatch system to check information, judge water level and dispatch drainage vehicles. Then, he plunged into the rain and started to rush to the scene.

  Chen Shiyong, 45, is the district leader of the Drainage Management Office of Hefei Urban and Rural Construction Bureau. He has been a party member for 25 years. During the flood season, he is responsible for the inspection and maintenance of drainage facilities within his jurisdiction and the emergency response to flood control. The water at the intersection has exceeded the warning water level. The transferred large mobile pump truck is racing against time to pump water and discharge it. Arrange personnel to inspect the wellhead and outlet as quickly as possible.

  The merchants along the street are about to be flooded, and there is no time to think about it. Chen Shiyong knocks on the door from door to door, earnestly persuading him to leave. The water level of Banqiao River was too high, and the water accumulated on the road surface for a long time was caused by backward flow. He took the lead in launching water for investigation and went down to block the drainage outlet. "The drainage facilities in the city are our key focus. Once a fault occurs, it is likely to cause urban waterlogging." Chen Shiyong said, "In the past, we ensured traffic. Now, we have to ensure safety."

  Chen Shiyong led the team members to work continuously for dozens of hours, during which mobile pump trucks were dispatched to help drain more than 30 times, helping to drain nearly 420,000 cubic meters of water. It’s still raining, but the accumulated water has gradually receded.

  In order to prevent urban waterlogging and flood season, Hefei Urban and Rural Flood Control Headquarters strictly implemented the 24-hour duty system and the leadership shift system in flood season. On the one hand, strengthen the inspectors who are on duty under the bridge and at the flood-prone points to ensure that the personnel are on the job and carry out emergency response at the first time; On the other hand, ensure that "the accumulated water is as little as possible and the accumulated water time is as short as possible".
