摘要
根据我国大陆58个Ms≥5级地震的震例资料．详细地研究了地震异常延续有效时间与持续时间的相关关系．给出了由地震异常持续时间计算地震异常预测的有效时间（即地震异常延续有效时间的最优估值）的公式，经多种数理统计方法检验，证明这一公式是可信、可用的.这为进一步深入开展地震异常前兆信息量的研究奠定了基础，同时也为日常地震会商中常需确定地震异常延续有效性问题．提供了定量分析判定依据。
By the data of earthquake cases with 58 Ms≥5 earthquakes in China's Mainland, this paper has studied the relative relation between the earthquake anomaly continuing effective time and lasting time in detail and presented the calculating formula of earthquake anomaly predicting effective timd (that is, the best estimating value of earthquake anomaly continuing effective time) by earthquake anomaly lasting time. Through inspection of many kinds of mathematical statistical methods, the formula has been proved to be reliable and avaiable, which established the foundation to further more develop the study of earthquake anomaly precursory information magnitude and also provided quantitative analysis basis for usually determining the problem of earthquake anomaly continuing effectiveness in daily seismological consideration. So this study might has real significances.
