摘要: 从固体潮理论出发证明了分点大潮倾斜潮的特征图像是一个椭圆,推广到一般朔望大潮也存在大潮倾斜椭圆,因而可以计算椭圆潮汐因子,滇西地震预报试验场及其附近地区的观测表明,椭圆潮汐因子异常与强震有良好的相关性,并从物理意义上进行了解释。

Abstract: Based on the theory of solid tide, this paper has proved the characteristics of vector of tilt spring tide observed during vernal equinox is an ellipse. Because during the spring tide of syzygy period also exists an ellipse, so the ellipse tidal factor may be calculated. The observations in Sichuan-Yunnan seismic experiment region and a nalysis results demonst rated that the anomalies of ellipse tidal factor are closely related to the strong earthquakes. The physical explanation of ellipse tidal factor has also been given.

Key words: ellipsetidal factor, Earthquake prediction, Correlation
