摘要: 根据地下流体地震前兆异常的特征, 按照分析预报方法研究“同一化”的技术思路, 从现有的分析预报方法中筛选出差分、从属函数、变差和变化率等4种方法, 用以判定地下流体的中期异常。文中介绍了4种异常判定方法的计算式与做法, 结合震例资料对这些方法进行了检验, 其效果良好。

Abstract: Basedon earthquake precursory anomaly characteristics of ground fluid, and according to the “identity ” technical thinking of analysis and Prediction method, four methods, suchas difference, subordinate function, variational difference and change rate, are screened out from current analysis and prediction methods. This paper introduced calculation form ula and methods for those four kinds of anomaly-judging method. Combining the earthquake case data, these methods are examined and the effect is good.

Key words: Ground fluid, Medium-termanomaly, Judge method
