摘　　要：本文应用铁岭地震台数字形变资料,对松辽盆及其附近地区4次中强震前的异常特征及其异常特征与上述4次地震的关系进行了分析,同时对地震前出现的异常时间、幅度、形态进行了研究。This article analyzes the anomalous characteristics before the four moderate-strong earthquakes in Songliao basin and its peripheral region with the observation data of the crustal digital deformation at Tieling seismic station. This article the unusual time, the scope, the shape which appears to the earthquake in front of have carded on the analysis, studies its.unusual characteristic and the above 4 earthquakes relations
