太阳轨道运动的2400年周期与轨道周期

通过对行星会合指数运动学方程生成的数据进行傅里叶变换, 得到了从年、十年、 百年、千年、万年到十万年时间尺度的周期, 发现这些周期具有后者是前者10n 倍的特殊倍乘关系. 如果将通过傅里叶变换得到的年时间尺度最显 著的周期4.96488a设为单位时间步长代入行星会合指数方程, 则可得到稳定 的2400年周期. 在此基础上由2400年周期振幅的差异性又构成了更长时间尺度的 10万年和40～41万年太阳轨道运动特征周期. 这对于揭示太阳轨道运动与太 阳活动的关系, 以及探讨气候千年尺度和轨道周期变化规律的机制具有重要意义. 

2400 Years and Track Cycles of the Sun's Orbital Motion

Through Fourier transferring of data from the planetary synodic index, it is found that the year, 10-year, 100-year, 1000-year, 10000-year and 100000-year scales of cycles have 10n multiple relationship. More interestingly, if we set the most significant period (4.96488a) on the year scale as the unit time step and put it into the equation of planetary synodic index, 2400 years cycle would be determined stably. On this basis, 2400 years cycle can be also assembled to form 100000 years and 400000～410000 years cycles of the Sun's orbital motion. This is helpful to unveil the relationship between the Sun's orbital motion and solar activity, and is significant to discuss the mechanism of climatic variation on the thousand years and orbital scales.
