  • Online:2010-04-25 Published:2010-04-20

摘要: 通过非惯性系中的角动量定理和惯性系中的角动量守恒定律分析天体的旋进,指出地轴的旋进与卫星轨道平面的旋进这两种现象同根同源,相互依存.

关键词: 旋进, 角动量守恒, 地球扁率, 卫星, 月球

Abstract: The precession of celestial bodies is analyzed in terms of moment of momentum theorem in non-inertial system and the law of conservation of angular momentum. It is pointed out that the origins for the earth' s axis precession and orbital precession of satellites are the same.

Key words: precession, conservation of angular momentum, oblateness of the earth, satellite, moon
