摘　　要：首先讨论了天体力学中常见的二体问题 ,然后将两个有限大小并具有任意质量分布的物体之间的引力作用简化成一个有限大小并具有任意质量分布的物体与一个质点之间的吸引 。The two body problem in celestial mechanics is first discussed in this paper.Then the gravitational interaction between the two objects possessed of any mass distribution is simplified as attraction between a limited size object possessed of any mass distribution and a particle.And finally,the object gravitational potential is presented with the method of expanding function in series.
