The proposal of "Healthy China" strategy putsforward higher requirements for College Physical Education teaching. At the same time, the popularization of scientific andtechnological achievements in sports colleges and universities has also resulted in one. Therefore, the author studies the impact ofthe popularization of scientific and technological achievements in sports colleges and universities from the perspective of healthyChina. College physical education should be guided by the "healthy China" strategic goal, change the teaching concept, improvethe teacher's own quality, reform the curriculum and evaluation system, cultivate students' health awareness and exercise habits,and then improve the overall quality of students' sports. It can promote the further development of the popularization of scientificand technological achievements in universities.展开更多

The level of agricultural science and technology depends largely on the degree of agricultural mechanization promotion. An agricultural country level depends on the degree of modern agricultural mechanization level of the application, and the era of mechanization in agriculture can not only save a lot of labor, reduce labor intensity, but also improve labor efficiency, and enhance resistance to natural disasters. The importance of agricultural mechanization technology in the scientific and technological achievements in agriculture is visible.展开更多

China's lunar exploration project(Chang'e project) was launched in 2004. At present, it has created a perfect end to the three phases of “orbiting, landing and returning”. A series of remarkable research achievements have been made on the basic issues of current lunar scientific research, such as the Earth-Moon space environment, lunar surface material, morphology,geological structure, lunar subsurface and internal structure, and the origin and evolution of the Moon, further deepening the human understanding of the Moon. This paper briefly reviews the development process of China's lunar exploration project,summarizes the main research results and scientific understanding, and finally prospects to the future development of China's lunar and planetary exploration.展开更多
