摘要
该文以变质量质点动力学方程 (密歇尔斯基方程 )为基础 ,建立了变质量少体问题的运动方程 ,并利用小参数方法得到了变质量少体问题的分析解。文中还将研究结果应用到彗星运动上 ,讨论彗星轨道中非引力效应。指出非引力效应会导致某些彗星轨道半长径和偏心率等产生长期和周期变化 ,这些变化将明显地影响彗星运动的周期以及过近日点的时间和地点 ,因此在这些彗星精密定轨和探讨其轨道动力演化时应当考虑这种非引力效应。
On the basis of Meshcherskii equation,the problem of few bodies with variable mass has been studied and its analytic solution has been also given by method of small parameter.Applying the results obtained in this paper to the motion of comets,discuss the nongravitational effect on the orbit of some comets.It is pointed out that the nongravitational effect will cause the secular and periodic variation of orbital elements a et al.The secular variation will obviously influence the period of comet moving around the Sun,the time and place of comet passing perihelion.Therefore the nongravitational effect should be considered in calculation of orbits of comets and in discussion of their dynamical evolution.Finally,also calculate nongravitational effect on the orbit of comet Encke.
