变质量少体问题及其应用
The Problem of Few Bodies with Variable Mass and Its Application
摘要
Abstract
On the basis of Meshcherskii equation,the problem of few bodieswith 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.关键词
