摘要
本文采用大森公式求解Ｋ、ｃ、ｐ三个参数，对云南１９６５年以来７１个地震序列进行研究。确定Ｐ＝０．８为前兆震群和正常震群的判定指标。利用Ｋ、ｃ、ｐ三参数计算序列理论曲线得到晚期强余震前差残曲线超出两倍均方差的结果。
In this paper, Omori's formula, N(t ) = K/( t + c )p is used to get the parameters K, c, p, and the judgement index of p=0.8 for normal and precursory earthquake sequences is determined through studying the 71 earthquake sequences in Yunnan since 1965. And then the pararneters K,c,p are utilized to calculated sequence theoretical curve, and the result that the residual curve before late strong aftershock exceeds mean square deviation by two times is obtained.
