固体潮的引潮力是一种重要的触发因素。

The tidal force of solid tide is an important triggering factor.

从牛顿时代以来，数学家和物理学家们就一直通过考虑海洋对引潮力的响应来研究海潮现象。

Since Newton’s time, mathematicians and physicist have investigated the tides by considering the response of the oceans to the tide-generating forces.

研究表明，大地震前震源区及其附近发生的几次显著地震易受固体潮引潮力某个方位附近触发。

The research results show that several significant shocks happened in source region and its vicinity before a large earthquake are easily triggered by certain directions.

连接它们的余迹，沿着NGC 5218逗号形状延伸至NGC 5216扭曲的旋臂，是引潮力互相作用的结果。

The debris trail that joins them, along with NGC 5218's comma-shaped extension and the distorted arms of NGC 5216, are a consequence of mutual gravitational tides.
