摘要
彗星的准确轨道运动的确定是个复杂而困难的问题,其显著特点是存在非引力效应。本文评述彗星的非引力效应研究进展,首先回顾这种效应的发现与解释,接着概述标准非引力加速度模型及其结果,最后简述其他非引力模型和讨论彗星爆发与喷流活动产生的短期非引力效应问题及展望。
Cometary accurate orbital motion is a complex and difficult problem. Its remarkable characteristic is the presence of the non-gravitational effect. In this paper, the progress of research concerned is reviewed. Firstly, discovery and explanation of the effect are summarized in brief. Then, standard non-gravitational acceleration models and their results are outlined. Finally, alternate non-gravitational models, some problems of short-term non-gravitational effect caused by cometary outburst and jet activity and the future prospect of this kind of studies are discussed.
