摘要

结合地震波记录原理,分析并讨论攀枝花台数字仪震相的一些物理特征,并使用MATLAB对攀枝花、长春台的地震资料做简单滤波分析,便于真实地反映地震波震相。参考川滇交界地区地质构造,总结出攀枝花台对多次地震记录震相分析的经验规律,为地震速报快速识别震相提供实用参考。
Combining the recording principle of seismic waves,we analyzed and discussed the physical characteristic of seismic phases recorded by digital seismograph at Panzhihua Seismic Station. Then we analyzed the simply fil-tering results of seismic data recorded by Panzhihua and Changchun stations to identify the real seismic phase by MATLAB. Reference for the geological structure in Sichuan-Yunnan area,we summarized the experience and regularity of analyzing the digital seismic phases recorded by Panzhihua Seismic Station,which could provide practical reference for rapid seismic phases identification in earthquake rapid report.
