摘　　要：在多年形变前兆研究基础上 ,对形变应变前兆的复杂性进行了讨论 ,并对典型的形变应变短临前兆实例进行了总结 ,找出其共性。以描述其共性特征为目标 ,给出了异常指标 K的计算模型 ,似可用该指标结合资料背景和实践经验进行综合分析 ,对某些On the basis of the researches on crustal deformation precursors for years, the complexity of the precursors are discussed, and some of their generality are found through the summarization of typical crustal deformation and strain precursors. For describing the common character, the calculating model of index K of anomaly is given. By means of comprehensive analysis of the K index, background data and the practical experience, it is possible that prediction for some strong earthquakes with magnitude more than 6 can be made in short term or even in imminent stage.
