摘　　要：采用模糊数学方法建立的动态从属函数，将地震前兆异常信息化作（０～１）之间的无量纲值，从综合的角度对常熟５１级地震震前前兆异常进行时、空动态演化的追踪分析研究，对进入中短期孕震阶段的前兆异常空间特征进行了探索。The anomalous information of earthquake precursor into the dimensionless values between 0 and 1 are transformed. The following analytical study for the time space dynamic evolution of precursor anomaly of M S 5.1 Changshu earthquake is made from complex view. The spacial characters of precursory anomaly in medium short terms of seismogeny stage have been studied.
