中文摘要：

太阳活动周期性韵律是否是行星系统对太阳表层造成的引潮力变化所导致，一直存在着争议．本文基于行星会合指数运动学方程，分析了行星系统对太阳的引潮力、引力的变化特征与规律．结果发现，引潮力造成的太阳表面物质加速度变化要比太阳自转变化造成的太阳表面物质加速度变化小2万倍．所以，造成太阳11年黑子活动周期和22年磁周期形成的主要原因，不是引潮力的变化，而是太阳自转速度的变化．随着行星系统的周期性运动，太阳系质心（P）与太阳质心（S）出现了重合与分离的22年周期性变化．在这个过程中，发生了太阳绕转角动量和太阳自转角动量间的转换，这个转换是导致太阳自转速度变化的主要原因．研究还发现，引潮力存在着237天的周期变化，与太阳活动约8个月的周期相对应．太阳引潮力的变化主要由木星、土星和金星、地球4颗行星的位置关系变化所决定，而太阳自转速度的变化主要由木星、土星、天王星和海王星的位置关系的变化而导致的．

英文摘要：

There exists a debate on whether or not the change of solar tide force is the main force to drive the solar activities. In order to calm down the debate, we calculate and analyze the planet junction index, the sun tidal force and Gravitation derived from the planets. It is found that the acceleration of the solar surface resulted from the solar tidal force is only one twenty-thousandth of that from the change of the sun rotation rate. Therefore, the change of solar tide force is not as important as the change of the sun rotation rate. The rendezvous and departure of the planets will result in the departure and rendezvous between the mass center of solar system and of the sun. Consequently, it brings about the separation and combination of the sun revolving angular momentum from or with the sun rotational angular momentum. This is the reason for the change of the sun rotation rate. The calculation also suggests a change of the solar tidal force with a periodicity of 237-days. This periodicity coincides with the solar activity periodicity about 8-monthes. It supports that the change of the solar tidal force may exact some effects on short-term solar activity. The change of the solar tidal force results mainly from the changes of the space relationship between the Jupiter, the Saturn, the Venus and the Earth. The change of the sun rotation rate is led mainly by the changes of the space relationship between the Jupiter, the Saturn, the Uranus and the Neptune.
