摘　　要：利用微扰法研究质点在有心力作用下圆形轨道的稳定性问题.对比分析了一阶与二阶两种近似条件下质点运动轨道的微扰相图,给出了两种近似条件下圆形轨道稳定性的条件.The use of perturbation energy particles in a circular orbit under the stability problem is studied Comparative analysis for the first-order and second-order approximations of two mass movements under the conditions of the perturbation orbit phase diagram is performed, the two conditions similar to the stability of the circular track conditions are presented.

关 键 词：稳定性 微扰法 相图
