行星摄动力对太阳活动的调制

Solar Activity Modulation by Planetary Perturbations

本文采用天体力学方法，考虑太阳系九大行星对太阳表面局部区域的摄动力，建立了太阳表面受行星起潮力的数值计算模型．利用此模型，针对历史上发生的100个大太阳耀斑事件，计算各耀斑区耀斑发生前后所受行星起潮力的变化．从耀斑发生的时间分布统计得到：在100个耀斑中，有75个耀斑发生在行星综合起潮力合力极大前后三天内．证明行星摄动对太阳活动有调制作用．最后，本文还对太阳活动起源、活动周期等问题进行了简要的讨论．

Using the method of celestial mechanics, considering the perturbative forces of the nine major planets on the flare regions, a dynamical model for the tidal forces on the solar surface is proposed. Calculations indicate that 75 out of the 100 arbitrarily selected large flares occtirred within 3 days before or after the local tidal force medmum. Our results demonstrate that perturbations of the major planets are an important factor affecting solar activity. The origin of solar activity could be linked with the global dynamical behavior of the solar system.
