摘要
本文用几种谱分析方法分析了从１９７６年７月－１９９２年９月期间的地球物理资料（日长变化，大气角动量）和太阳活动（Ｗｏｌｆ数）及１９７６年７月－１９８７年１２月的日冕指数。结果证实所有序列中呈现出４０－６０天的振荡。同时也表明：它们的振幅和周期是随时间变化的。本文研究了谱结构的时空分布和讨论地球物理现象与太阳活动之间的可能联系。
The analysis of geophysical data and solar activity(Wolf) from July 1976 to cept.1992 as well as Corona index from July confirims the presence of oscillations with period ranging from 40 to 60 days in all these series.It is shown,at the same time,that their amplitudes and periods change with time.In this paper,we examine the spatial and temporal distribution of spectral structure and investigate possible connections between geophysical phenomena and solar activities.
