摘　　要：为了分析和研究数字地震波信号的频谱分布特征,开发了地震波信号频谱分析软件(CALM P),并对辽宁岫岩地震和山西台网记录到的2001年至2003年的地震进行了分析处理,以期发现数字地震波信号的频谱分布规律。In order to analyze and study the distribution characteristic of frequency spectrum of digital seismic wave signal, a software for frequency spectrum analysis of digital seismic wave signal（CALMP） is developed. Some analysis and processing to data of Xiuyan,Liaoning earthquake and some earthquakes recorded by the Shanxi Seismic Network from 2001 to 2003 are made, trying to work out distribution law of frequency spectrum of digital seismic wave signal.
