摘要: 由扣人心弦的“嫦娥一号”几次变轨,使笔者追寻一个问题:即决定椭圆运动周期的最简单公式是什么?进而对卫星的圆运动问题,椭圆运动问题的普遍公式作了一个小结.这对于学过普通物理的大学生都会有帮助.

关键词: 卫星, 椭圆运动, 角动量守恒

Abstract: A What is the simpl the circle and elli problem is considered from changing trajectories of several times of "Chang E number one". est expression of determining the period of ellipse motion? A summary for the general formulae of pse motions is proposed. This is useful to the undergraduates having learned the general physics.

Key words: satellite, ellipse motion, conservation of angular momentum
