摘要
本文导出了在一个旋转质量所产生的引力场中运动质点的三维轨道角动量的表达式.据此,作者分析了太阳自转对地球公转角动量(即轨道角动量)的影响,指出:(1)太阳自转对地球公转有一种微弱的同向感应作用;(2)太阳自转会引起地球公转角动量不守恒.最后,对公转角动量的变化,进行了计算.
A formula of the three-dimension orbital angular-momentum of a moving particle in the gravitational field produced by a rotating mass was derived. On this basis, the author analyzed the influence of solar rotation on the orbital angular-momentum of the Earth, and pointed out: (1) solar rotation produces slightly an induction on the orbital movement of the Earth in same direction; (2) due to this solar rotation, the orbital angular-momentum of the Earth is unconstunt. Finally, the changes of the orbital angular-momentum of the Earth were computed.
