| 摘 要： | 本文计算了由太阳系大行星轨道运动引起的日心相对于太阳系质心的轨道运动角动量变化率j_⊙,在理论上对j_⊙作展开,表明它存在多项短周期变化,与太阳黑子资料的分析结果相比较,两者结果是符合的,它们具有一致的谱结构。因此,行星的轨道运动对太阳黑子活动存在动力作用的可能性又进一步得到了验证。

| Abstract: | The rate of change of the angular momentum of the Sun's center about the center of mass of the solar system caused by the overall planetary orbital motion denoted by j has been calculated in the ecliptic coordinates of barycenter of the solar system with reference to the epoch JD = 2451545.0. Various short periodicities were shown in the polynomial of J It has indicated from the adoption of the multi-stage filter and the power spectrum analysis with Marple Algorithm that the results of same period narrow band filtering of J series and relative sunspot numbers (SP) series are closely correlated with each other, and the coincidence of spectral character between these two series is comfirmed- The periodicities approaching 314.7 and 149.9, 118.1, 94.5 days obtained from Figure 5 and 6 coincide closely with the theoretical results of No. 3-6 in Table 1. In conclusion, it is highly probable that the orbital motion of the planets is a very important dynamical factor affecting sunspot activities. |
