中文摘要：

运用法国巴黎默东天文台记录的暗条目录资料构造了一个时间精度为每天的暗条数目序列，选用Scargle周期图和Morlet小波变换两种周期方法研究了这个序列的周期性，发现其存在4个显著的周期，它们分别是1557天、1141天、795天和367天，详细分析了这些周期的时变特征，并简单讨论了其中个别典型周期的相位、物理机制和相互关系．

英文摘要：

By using the Meudon filament catalogues we reconstruct a daily sequence of filament counts from July 1957 to December 2004 and perform a periodicity analysis with the methods of Scargle periodogram and Morlet wavelet transform. As a result, four prominent periods are found around 1557, 1141, 795 and 367 days. We analyze their temporal variabilities in detail and discuss some typical ones＇ phases, physical implications and mutual relations briefly.
