| 摘 要： | 断层形变短临前兆表现形式是多样的，并作了初步分类，丛集性高频波动是其一种重要现形式，探索了这种前兆信息的提取思路和方法，认为信息丛集度Ｃ是描述这种前兆短临信息，熵值积分平滑值Ｇ是描述中短信息较理想的特征量，震例学表明第二类前兆具有较好的预报效能，对异常判据了初步探索。

| Abstract: | It is various while showing short-impending anomaly of fault deformation.An important expression form is cluster high-frequency fluctuation. The idea and the method to obtain the precusory information have been discussed. Information cluster degree C and smooth value G of entropy integral are characteristic values to describe short-impending information and medium-short term one for the precusor,respectively. |
