摘　　要：行星会合指数和太阳引潮力指数是行星系统相对于太阳的两个重要指标,在分析行星系统对太阳影响方面具有重要意义.为探究行星系统会合运动及其引发太阳引潮力的周期吻合性,本文对行星会合指数和太阳引潮力指数两指标进行数值模拟,提供了百年、千年尺度的时间序列.对1450—2000AD期间的行星会合指数和太阳引潮力指数进行索周分析,显示行星会合指数存在显著的准19.88年、39.37年、12.94年、25.54年的周期规律,其中19.88年、39.37年的周期性较强、12.94年、25.54年的周期性较弱;太阳引潮力指数存在准11.99年、24.04年、35.99年、48.03年的强周期和4.0年、5.97年、7.98年、16.01年的弱周期.同时,利用功率谱和Morlet小波分别对行星会合指数和太阳引潮力指数进行周期性分析,分析结果与索周分析结果一致.行星会合指数和太阳引潮力指数存在相近的周期性规律又存在不同的周期性特征,反映了两指标的变化特征;行星对太阳正、反垂点产生大小近似相等、方向相反的引潮力,当行星会合指数处于极大或极小值时太阳引潮力指数都将达到极大值.行星对太阳引潮力的复杂性导致太阳引潮力指数具有多周期性特征,这些周期性规律有助于分析太阳活动.行星会合指数和太阳引潮力指数为进一步研究行星系统对太阳影响及太阳活动提供新思路.The planet juncture index and solar tidal force index are two important indicators of planetary system relative to the sun,which are of great significance in analyzing the impact of planetary system on the sun.To explore the periodic coincidence between the rendezvous and dispersed motion of planetary system and the solar tidal force,this paper provides the time series of the planet juncture index and solar tidal force index at the centennial and millennial scales by numerical simulations.The cycle exploring analysis of the planet juncture index and solar tidal force index during 1450~2000AD shows that there are significant quasi-19.88,39.37,12.94and 25.54 year cycles in the planet juncture index,with stronger cycles of 19.88 and 39.37 years and weaker cycles of 12.94 and25.54 years;the solar tidal force index exists with strong cycles of quasi-11.99,24.04,35.99 and 48.03 years and weak cycles of4.0,5.97,7.98 and 16.01 years.Meanwhile,the power spectrum and Morlet wavelet are used to analyze the planet juncture index and solar tidal force index,respectively,which the results of the analysis are consistent with the results of the cycle exploring analysis.The planet juncture index and the solar tidal force index have similar periodic patterns but different periodic characteristics,reflecting the variability of the two indicators;the planets can produce approximately equal and opposite tidal forces on the sun’s forward and reverse points,and the solar tidal force index will up to a maximum value when the planet juncture index reaches the maximum or minimum value.The complexity of planetary tidal forces on the sun leads to a multi-periodic characteristics of the solar tidal force index,and these periodic patterns are useful for further analysis of solar activity.The planet juncture index and solar tidal force index provide new ideas for further research of the influence of planetary systems on the sun and solar activity.
