| 摘 要： | 分析了新疆和田地区１９９２年４月５日发生的Ｍｓ５．９地震和同年９月２日、１２月２５日发生的Ｍｓ４．６级地震的震前地倾斜异常情况。利用迭代法对地震平静年份的资料进行处理，做出正常背景曲线并与异常图象比较，收到了良好效果。另外还各单位介绍了田地区的地质构造背景及历史地震活动，并对常用处理资料方法的预报效能以及异常量大小和震级的关系进行了讨论。

| Abstract: | On April 5, 1992 .a Ms 5. 9 earthquake occurred in Hetian of Xinjiang .and other two Ms 4. 6 earthquakes occurred on Sept. 2 and Dec. 25, respectively in the same year. Groundtilt anomalies that occurred prior to the earthquake were captured. After handling the data of seismicity quiet years with iterative method and comparing the normal background curves with abnormal ones, better results were obtained. The background of geologic structure and historical seismicities in Hetian area, the prediction ability of ordinary data - processing method, the correlations between the abnormal scales and magnitudes were discussed. |
