摘要
本文讨论了太阳系行星自然卫星运动的稳定区域问题,对逆行卫星的实际稳定区域较大的原因给出了一种解释,基于太阳-行星-卫星圆型限制性三体问题模型,对太阳系所有自然卫星是否处于稳定区域问题作了讨论,从动力学角度而言,这一讨论与密近双星中两恒星之间的物质(相对于卫星)交换规律有紧密联系。
In this paper, thc problem of thc stable regions of motion of the natural satellites in the solar system is discussed and an explanation about the reason that there exists a larger stable region for the motion of retrograde satellites is given. Based on the model of the circular restricted three-body problem consisting of Sun-planet-satellite, it is discussed whether each of satellites in thc solar system is situated in the stable region or not. This discussion, from a dynamical viewpoint, has a close connection with understanding of thc mass transfer between two stars in the close binary system.
