【摘要】 根据楚雄台倾斜固体潮潮汐分析的结果，发现地震前潮汐相位滞后出现３—４个月的短期减小。从构造物理学上探讨了潮汐相位滞后、介质粘滞性与潮汐形变的关系，并且用楚雄应变潮调和分析结果即应变潮汐振幅因子迅速增大所证实。研究表明，潮汐相位滞后用于地震预报是一种很有前途的短临预报方法。更多还原

【Abstract】 rom the analysis of solid tide recorded in Chuxiong seismic station, it is discovered that the reduction of 3-4 months for tide phase lag appears before earthquake. The relation of tide phase lag, medium viscosity and tide deformation has been explored from tectonophyics, which is verified by the results of harmonic analysis of strain tide in Chuxiong station, namely the strain tide and amplitude factor increase rapidly. The study shows that the tide phase lag is a hopeful method to short-impending earthquake predictions.更多还原
