摘　　要：重复地震在地震学的研究中已得到广泛的应用。国家"九五"、"十五"计划期间,完成了数百个地震台站的数字化建设工作,为重复地震的广泛开展提供了良好的天然条件。为了有效发挥重复地震的作用,该文根据重复地震的定义和识别方法,研制了重复地震的识别与相关分析软件,给出了重复地震在地震预测研究中的一个应用例子。检验表明利用该分析软件可以充分利用数字地震波形开展相对高精度的地壳介质分析。Repeating earthquakes have been broadly applied in the study of seismology. Hundreds of digital seismic stations have been built from the ninth and tenth five years period in China,which offer a very good condition for the study of repeating earthquakes. A software for identifying and analyzing repeating earthquakes has been developed in order to bring into play the studying role of repeating earthquakes based on the defining and identifying method about repeating earthquakes, and an actual application example of repeating earthquakes is given in the earthquake forecasting. The test shows that the software about repeating earthquakes can relatively achieve high-precision analysis of crustal medium using digital seismic waveform data.
