| 摘 要： | 本文利用《地震前兆信息处理与软件系统ＥＩＳ２０００》的方法分析了辽宁地区的地形变资料，发现在１９９９年１１月２９日岫岩５．６级震前短临异常特征明显，数字滤波，自适应阈值，多项式拟合，周期分析等数学处理方法均显示异常，为省局地震预报室的成功预报提供了重要的依据。

| Abstract: | The deformation data in Liaoning Province is analyzed by using the method referred in EIS2000. It is found there exist obvious anomalies of short-term and imminent data such as digital filtering, polynomial curve fitting,adaptive threshold value, etc., they all show the anomalies prior to the Ms5.6 earthquake. |
