| 摘 要： | 对1999年以来新疆定点形变观测资料进行了分析。重点以基于突变异常理论的异常强度方法，对近期一组中强地震活动前后形变场的异常变化进行了动态分析，表明形变资料能够反映出一定程度的中短期、短临前兆异常，异常强度方法能够检验出大于阈值2的短期异常。

| Abstract: | We analyzed the datum of fixed-point deformation of Xinjiang since 1999. Based on the anomalous intension method of break anomalous theory, the anomalous changes of deformation field before and after a group of medium-strong earthquakes' activities in the near future were analyzed dynamically, the result show, the datum of deformation can reflect the medium-short term and immediate precursory anomalies, the short term anomalies of larger than 2 can be tested by anomalous intension method. |
