【摘要】 用数值拟合的方法对１９６６年以来７６个ＭＬ≥５．５地震序列的衰减特性进行了较详细的研究，提出从ｈ值的逐日时间扫描和逐日累积时间扫描两个方面去把握地震序列的衰减过程并将其用于强余震（含双震）的预测和震型的快速判定。更多还原

【Abstract】 The attenuate characteristic of 76 earthquake sequences of ML≥5. 5 since 1966 is studied using the method of numerical fit. It is indicated that the attenuate process of earthquake sequence is hold from both daily time scan or cumulate one of h value, which is made use of predicting strong aftershock (including double earthquake) and fast discriminating seismic type.更多还原
