摘要
由环面坐标下的Ｌａｐｌａｃｅ方程得到三体问题的引力势分布，然后根据Ｌａｇｒａｎｇｅ函数，建立了受摄动体的运动微分方程组。
The gravitational potential distribution of the three body problem is obtained by using the Laplace equation on the toroidal coordinates.The differential equations on the bodies movement under the perturbations are established,and the results are of universal significance.
