摘　　要：本文研究了不同地震序列类型的早期特征。得到了利用地震序列第一天特征来判别地震类型的两个指标:地震频度N和震级级差△M。研究结果表明,这两项指标简单明了,使用方便,且具有较好的判别效果,对地震现场工作具有一定的意义。The early features of different types of earthquake sequence are studied in this pa-per.Two indices to distinguish the earthquake types are obtained:earthquake frequency N and magnitude difference AM. The results show that two indices are not only simple, clear,and convenient, but also are of better effect for distinguishing different types of earthquake sequences.
