摘要
本文通过对目前已发表的47条狮子座流星雨的历史记录的分析,得出流星雨有一个以600年为一完整周期的和谐体系,其中含有200年、300年和100年三个小循环周期。这些周期的发现,可解释历史上的某些存疑问题,对认识和探索这群流星群的运动规律有积极的作用,对于预报流星雨工作亦有助益。本文还对该流星群的结构和坦普尔(Tempel)彗星的某些影响作了初步探讨。
Based on 47 published historical records of Leo shower and an analysis of them, the author finds a harmonious system of this meteoric stream which takes 600 years as a complete period, and in the complete period there are three recurrent sub-periods of 100 years, 200 years and 300 years respectively. By this discovery, some problems left for future consideration can be interpreted, the law of the motion of the meteoric stream can be understood, and Leo shower can be predicted as well. The author goes further into the structure of the meteoric stream and some influences of Tempel comet.
