摘要
用分析力学方法导出绕地心作圆周运动的杆状同步卫星绕质心运动的微分方程并讨论了它的摆动周期,得出不可能有在地球子午面内的卫星摆动,因而不可能有在地球子午面内的卫星摆动周期的结论.
The differential equation of shaft-shaped satellite moving circularly around the Earth is studied by analytical mechanics, and its swing period is given. It is pointed that the swing in the meridian plane of the Earth is impossible.
