摘　　要：应用速率合成法对山西南部数字化形变观测资料进行处理,通过山西南部地区显著地震对比分析,结果表明,震前异常特征不明显的同类型观测数据,经过速率合成后,群体异常信息更加突出,显示出较好的映震效果。The data of digital deformation observation in the south of Shanxi Province are processed by using rate synthesis method.Through the comparative analysis of significant earthquakes in the south of Shanxi Province,the results show that the same type of observation data with no obvious abnormal characteristics before earthquakes are more prominent after rate synthesis,which shows better seismic reflection effect.
