| 摘 要： | 应用微动态异常频次、Ｍ２波振幅比等方法，对巢湖１４＃井水位１９８７～１９９７年进行了全过程的分析研究。研究结果表明：在华东几次中强震前，该井水位的微动态异常频次在地震前３～４个月有明显增高的异常显示，而水位Ｍ２波振幅比在地震前也存在３～４个月的下降异常。由此可以认为该井有可能成为华东及东部沿海５级以上地震的灵敏井点之一，而且在地震的短期预测方面可能会提供有益的异常信息。

| Abstract: | All processes of 1987～1997 water level of Chao lake No 14 well are analyzed and studied using the methods such as anomalous frequence of the level microdynamic and M 2 wave amplitude ratio It is concluded that the anomalous frequence of the well microdynamic obviously increased and M 2 wave amplitude ratio decreased in 3～4 months before several moderate earthquakes of east China It is possible that the well is one of sensitive wells to M S≥5 0 earthquakes of east China and coast area |
