大行星轨道运动与太阳黑子数的中长周期变化

本文对不同序列的太阳黑子数资料作了分析研究,计算得到了可能的太阳黑子活动的中长周期变化,并分别与由大行星轨道运动引起的日心轨道角动量变化的周期进行比较,发现二者具有比较一致的谱结构。基于本文的讨论和文17]的结论,我们进一步认为大行星轨道运动是太阳黑子数周期性变化的可能的外部因素。

The Orbital Motion of Major Planets and the Long Periodic Change of the Relative Numbers of Sunspot

In this paper, we have analysed the various data of sunspots (SP), and obtained the probable periods of sunspot activity of about 200 yr,85 yr and 60 yr. Compared with the rate of change of the angular momentum of sun about the center of mass of the solar system j , we found both the series of SP and j have the coincident spectral character According to our research on the cause of the chief period of sunspot numbers, it proved that the orbital motion of the major planets is an very important external factor in causing the periodic change of the relative numbers of sunspot.
