| 摘要: |
| 讨论了引潮力与中、强地震发生的可能关系。进行了水平引潮力极值条件分析，研究了满足水平引潮力极值条件下的天体时角表征的地震活动可能存在的应力调制。其技术途径是在一定的时窗内，通过地震目录资料的天体时角计算，求出满足水平引潮力极值条件时所出现的调制地震活动场的时空特征，继而研究这些时空特征与未来中强地震三要素的关联，以期获取地震预测信息。 |

| Abstract: |
| Based on analysis of the horizontal tidal force extreme condition symbolized by globe time angle the modulation of earthquake activity is discussed in this paper． By the calculation of globe time angle for micro earthquakes satisfying the condition of the horizontal tidal force extreme modulation，some prediction messages of a recent moderate or strong earthquake in the research region are hoped to be obtained． |
| Key words: The horizontal tidal force extreme condition Globe time angle as a token of extreme modulation Earthquake forecast |
