Nine departments introduced measures to reduce the burden: primary school students sleep at least 10 hours a day.

  Yesterday, the Ministry of Education and other nine departments jointly issued "Measures to Reduce the Burden of Primary and Secondary School Students", with a total of 30 articles. This "burden reduction order" clearly stated for the first time that students should not bring their mobile phones into the classroom, and there are clear "scales" for the total amount of written homework, students’ sleep time and the number of exams. For example, primary school students do not leave written homework in grades one and two, homework in grades three to six does not exceed one hour, and primary school students sleep for at least 10 hours every day.

  Put an end to "non-zero starting point" teaching

  Strictly control the number of exams

  The "30-article burden reduction" clearly requires that primary and secondary schools should strictly implement the national curriculum plan and curriculum standards, start all the prescribed courses, and must not arbitrarily increase the teaching difficulty and speed up the teaching progress, and put an end to the "non-zero starting point" teaching. In the compulsory education stage, it is strictly forbidden for schools to set up key classes, fast and slow classes and experimental classes in any name, standardize the implementation of random and balanced classes for students, and allocate teachers in a reasonable and balanced way.

  Schools should resolutely control the number of examinations. The school can organize a unified examination every semester in the first and second grades of primary school, and no more than two unified examinations every semester in other grades. It is not allowed to organize a unified examination that is selective or linked to further studies in primary schools. The examination content is determined strictly according to the curriculum standards and basic teaching requirements, and there are no eccentric questions. Grade evaluation of test scores is implemented, and it is strictly forbidden to publish students’ test scores and rankings in any form or manner.

  All localities should further promote the full coverage of compulsory education schools to enroll in the nearest school without examination, and it is strictly forbidden to organize examinations and select students in various names, and it is strictly forbidden to use the training results of training institutions as the basis for enrollment.

  No written homework in grades one and two.

  Parents are not allowed to evaluate and correct homework on their behalf.

  In the past, the workload requirements were also specified, such as "no more than half an hour", but some schools implemented this requirement as "single subject", that is, the workload of each subject did not exceed half an hour, so that the total workload of all subjects far exceeded the regulations.

  The "30 articles of burden reduction" clearly controls the "total amount of written work". There is no written homework in grade one or two in primary school, no more than 60 minutes in grade three to grade six, no more than 90 minutes in junior high school, and the homework time in senior high school should be arranged reasonably. The difficulty level of homework should not exceed the requirements of the curriculum standard, teachers should not assign repetitive and punitive homework, and parents should not assign homework or ask parents to evaluate and correct homework on their behalf.

  According to the new regulations, off-campus training institutions are strictly forbidden to train beyond the class, and it is strictly forbidden to link the training results with the enrollment of primary and secondary schools, and it is strictly forbidden to organize and hold subject-level examinations, competitions and rankings for primary and secondary school students.

  Schools around the country can establish a flexible school leaving system, provide students with a variety of after-school services, arrange students to participate in various interest groups or music, sports and art activities, and it is strictly forbidden to turn after-school services into collective teaching or collective remedial classes.

  Put an end to the problem of off-topic in the college entrance examination

  Teaching and enrollment will be linked to "burden reduction". The new regulations require that all localities fully implement the enrollment mode of high school based on the scores of junior high school level examinations and comprehensive quality evaluation, rationally allocate high-quality high school enrollment places to ordinary junior high schools and improve the implementation rules. The enrollment of private primary and secondary schools is incorporated into the unified management of school approval, and enrollment is synchronized with public primary and secondary schools.

  The grading examination of academic level and the proposition of college entrance examination in ordinary high schools should be based on the curriculum standards of ordinary high schools and the requirements of talent selection in colleges and universities. All localities should innovate the form of test questions, increase comprehensive, open, applied and exploratory test questions, strengthen situational design, and put an end to eccentric questions.

  High school students sleep more than 8 hours a day.

  The "burden reduction order" also has clear requirements for students’ sleep time. Families should ensure that primary school students sleep no less than 10 hours a day, junior high school students not less than 9 hours, and senior high school students not less than 8 hours.

  Liu Xiuying, director of the Family Education Research Institute of China Youth Research Center, said that sleep is the most comprehensive and effective rest, and adequate sleep can improve children’s brain power.

  For the first time, it is clear that mobile phones are forbidden in class

  The "burden reduction order" proposes that students should be standardized in using electronic products, and it is forbidden for students to bring mobile phones into the classroom. This is the first time that relevant policies have made it clear that "mobile phones are not allowed in the classroom".

  Nine ministries and commissions also advise families to fulfill their educational guardianship responsibilities, guide children to use electronic products reasonably, go to healthy websites, not indulge in online games, and do not use mobile phones to screen. Don’t let children watch TV for a long time, ensure that primary school students sleep every day, work and rest on time, don’t stay up late, eat less snacks, don’t be picky about food, and don’t compare with others.

China Star | Breakthrough Difficulties! These "black technologies" support the docking of "boats" with "big stations"

  CCTV News:Tiangong’s "reunion" is not only the rendezvous and docking mission of the first manned spacecraft in the application and development stage of China Space Station, but also the first radial rendezvous and docking mission under the T-shaped configuration of the space station’s three cabins. Compared with the past, what are the difficulties of this rendezvous and docking mission? How do researchers guarantee it?

  Difficulty 1: radial docking of the "T" space station assembly for the first time.

  The first radial rendezvous and docking with the three-cabin space station

  Previously, China’s spacecraft rendezvous and docking in space were mostly in the horizontal direction, while the radial rendezvous and docking can be understood as docking from the vertical direction. Although both Shenzhou 13 and Shenzhou 14 have completed radial docking before, this is the first time that Shenzhou 16 has made radial rendezvous and docking with a three-cabin space station.

  Jian Yao, chief designer of the docking mechanism subsystem of Shenzhou manned spacecraft:For the first time, we carried out radial docking on the "T" space station assembly. There is a big eccentricity in this docking, which is also a brand-new challenge.

  Difficulty 2: The docking target configuration is complex and the tonnage is huge.

  Radial rendezvous and docking is equivalent to a "space collision"

  Rendezvous and docking in space, figuratively speaking, is that two spacecraft "collide" in space. Therefore, the quality of the two will have a great impact on the whole docking process. Previously, the Shenzhou 14 manned spacecraft docked at the space station radially, and the docking target of the spacecraft was 47 tons. This time, the Shenzhou 16 manned spacecraft will rendezvous and dock radially with the 100-ton space station assembly. Facing the multi-configuration, large tonnage and large eccentricity docking target, the docking mechanism is a brand-new challenge in capture, buffering and rigid connection.

  Jian Yao, chief designer of the docking mechanism subsystem of Shenzhou manned spacecraft:By increasing the configuration of controllable dampers, we can control the load during docking and ensure that astronauts and onboard equipment can withstand the impact caused by docking collision.

  Difficulty 3: The huge size of the space station interferes with the spacecraft sensor.

  Measuring equipment helps the sensor to improve its recognition ability.

  In the process of rendezvous and docking, shenzhou spaceship needs to rely on many measuring sensors to judge the position and direction, and many of these sensors are based on the background of the sun or the universe. Because the spacecraft is docked from below the space station, the huge size of the space station will block the sun and reflect the sunlight, which will interfere with the sensors on the spacecraft.

  Zhang Yi, Deputy Director of shenzhou spaceship Guidance Navigation and Control Subsystem:In this respect, it is necessary to rely on the anti-interference characteristics of the spacecraft, including some target recognition capabilities. In other words, it can identify whether the measurement target I want or some other occlusion target comes in.

  "Black Technology" Behind shenzhou spaceship’s Fast and Accurate Docking

  Before shenzhou spaceship docked with the space station, every attitude adjustment would bring speed change. It is as difficult for human eyes to observe this change as it is to observe the change caused by using the power of ants to push a floating elephant. This requires a high-precision accelerometer to sense small changes in speed and direction. What is this "black technology"?

  Yu Huanan, chief designer of 33 high-precision accelerometer combinations of China Institute of Aerospace Science and Technology:This turntable is to simulate the spacecraft’s attitude changes during the whole flight, and it will have an acceleration input.

  Reporter:Now the module we put on it, is it a product that has actually been in space?

  Yu Huanan, chief designer of 33 high-precision accelerometer combinations of China Institute of Aerospace Science and Technology:Yes, this is the product of Shenzhou XIII’s space flight. After the flight test, these data are further calibrated and compared with the delivered data, which provides a good guiding direction for us to explore or improve the product.

  In recent years, with the increasing in-orbit time of Chinese astronauts, higher requirements have been put forward for all kinds of shenzhou spaceship components that are also on standby in orbit. Through continuous innovation and upgrading, researchers keep up with the rapid development of China’s space industry.

  Yu Huanan, chief designer of 33 high-precision accelerometer combinations of China Institute of Aerospace Science and Technology:For example, radiation and the temperature environment in space will have an impact on the devices and structures of products. At the beginning of design, it should be considered to ensure that the product can have long-term working reliability.

  Yu Huanan said that the accelerometer developed by No.33 Institute of the Third Hospital has been in use since the Shenzhou-1 spacecraft was launched in 1999. It has experienced iterative processes such as stability improvement, vacuum environment adaptation transformation and temperature environment adaptation improvement, and has become one of the most reliable components of Shenzhou Feitian.

  Yu Huanan, chief designer of 33 high-precision accelerometer combinations of China Institute of Aerospace Science and Technology:The new generation of spacecraft must pursue higher performance and higher integration. This time, we integrate the circuit and meter into other stand-alone computers in the navigation control system of the spacecraft in a new form to support the engineering development of a new generation of spacecraft. Through these continuous innovations, we can better meet the needs of the motherland in space applications such as space station construction and deep space exploration.
