摘要
应用辽宁地震台网记录的爆破与地震数字资料,采用小波计算方法,对该区域记录的爆破与地震计算S波拐角频率,将计算结果与前期采用PITSA软件得到的结果进行比较,试图获得爆破与地震识别的定量指标。
Based on the digital data of explosion and earthquake recorded by Liaoning Digital Seismological Network, the S wave corner frequency calculation of these records was performed by the means of wavelet analysis. We have compared the result of wavelet research and PITSA program in order to seek for a quantitative index in the recognition of explosion and earthquake.
