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.

阐述如何利用地震台观测得到的地倾斜矢量图对固体潮半日波进行潮汐导纳分析。

The tide admittance analysis for the semidiurnal wave of the earth tide by use of the vector pattern of ground tilt observed at seismostations is expounded.

异常形式主要表现为水位升降，水位固体潮形态畸变和相位错动以及典型的“临震回跳”等。

The anomaly pattern is mainly expressed as the elevation and subsidence of water level, distortion and phase disturbance of solid tide form of water level, and typical 'impending rebound "and so on."

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.

对云龙台的水管倾斜仪观测数据进行了倾斜固体潮的潮汐分析，发现EW和NS两个分量的振幅因子异常变化与地震有较好的对应关系。

Based on the water tube tiltmeter observatory data, the author analyses the ground tilt tide, finds that the abnormal change of amplitude factors of EW and NS componts is corresponding to earthquakes.
