行星环动力学

Planetary Ring Dynamics

行星环动力学的研究对揭示太阳系、星系的形成和演化有重要的意义。旅行者2号的行星际探测，极大地丰富了我们对行星环的认识，给行星环动力学的研究带来了活力。文中综述了在行星轴对称势、环自引力势、环粒子碰撞、卫星摄动等因素影响下的行星环的研究方法及研究进展。

The study of planetary ring dynamics may be helpful to our understanding both the origin and evolution of the solar system and the galtales. The planetary encounter of Voyager 2 greatly enriches our knowledge of planetary ring systems, and challenges the study of ring dynamics. We review the progress on the reaserch of major ring dynumics under the influnces of the gravitational fleld of the oblate primary plallet, the self-gravity of the ring, ioter -particle coilisioas and satellite perturbations.
