近几年,随着神五神六神七的成功发射,探月计划的逐步实施,我们用自己的实力向世界证明了中国的航天事业已经直追世界先进水平.光环虽有,但不能阻止我们继续创造辉煌的脚步.现代竞争离不开科技的支持,而航天技术水平在一定程度上反映着一个国家的科技实力.对“万有引力和天体运动问题”的研究依旧是物理学科中的重中之重.万有引力及天体运动问题一直是物理教学中的重点,也是难点.
In recent years, with the successful launch of the gods and gods, six gods and gods, and the gradual implementation of the lunar exploration program, we have proved to the world our own strength that the aerospace industry in China has caught up with the world advanced level .Although the aura can not stop us Continue to create brilliant footsteps.Modern competition can not be separated from the support of science and technology, and aerospace technology to a certain extent, reflects the scientific and technological strength of a country.Research on “gravitation and celestial movement ” is still the weight of physics The weight of gravity and celestial movement problems has always been the focus of physics teaching, but also difficult.
