地球自转变化中的太阳物理效应

对太阳活动和太阳风影响地球自转的研究现状作了评述。首先了地球自转变化的表示和测定方法，引起地球自转变化的各种扰动源以及自转长期变化中的潮汐效应和非潮汐效应。然后对地球自转变化中的太阳活动周期调制，太阳耀斑可能引起地球自转突然减速以及太阳风能否影响地球自转等问题的国内外研究现状和结果、分析作了谰论性阐述，最后作了简要总结。

The Effect of Solar Physics on the Variation of the Earth Rotation

The present situation of the study concerning the effects of solar activity and solar wind on the variation of the earth rotation is described in this paper. At first, the expressions and the measurements of the variation of the earth rotation, the disturbing sources causing the variation of the earth rotation, as well as the tidal and the non-tidal effects in the long term variation of the earth rotation are explained. Then, the currellt researches about the modulation of periods of solar activity in the earth rotation, the possible sudden retardation of the earth rotation by solar fiares, and the possibility of inIluence of solar wind on the earth rotation are reviewed. And a brief summary is given finally.
