By the action of gravitation or other forces, the acceleration of the body in move is anisotropic.

在引力或任何其它力的作用下，运动物体的加速度是各向异性的。

On the basis of the method of action-angle variables the conditions of closed orbits under the action of general power-type gravitation potential are discussed on this paper.

本文采用作用角变量的方法，讨论了闭合轨道在一般幂次型引力势作用下的情况。
