摘要
笔者曾提出了引潮力——重力共同作用是驱动板块运动的主要力源假说。在本文中，作者又把引潮力——重力共同作用原理运用到地震时、空分布原因的研究上，提出了地震机理是由内、外的共同作用：即重力与引潮力的结合；岩石圈与水、气圈的相互联系上。本文主要分析了全球浅源大陆地震在空间、优势层位上分布规律之稚由；并运用力学分析原理，对中、外学者所研究的发震时刻对固体潮表示响应的现象，给出了受力岩石在引潮力——重力共同作用下其结构面力学特征的根据。进而说明引潮力——重力共同作用在引发甚至孕育地震中的重要作用，也表明了引潮力——重力共同作用具有全球构造力的深刻意义。
The author has put forward the hypothesis that the driving force of platesmovement is given by tidal force and gravity co-operatlon. In this paper,the hypothe-sis principle is also applied to research seismic mechanism. The authors mainly study the reason whv most of the continental earthquarke oc-curied within 20°-50°S,and explain the reason why seismic time of shallow-focusearthquake is associated with earth tidal.Both of the reasons would be regard as the re-sult of tidal attraction and gravity co-operation,The authers try to prove that tidalforce-gravity co-operation detonates or breeds earthquake.
