| 摘 要： | 该文对2009年至2010年昔阳地震台体应变和测震数采并行观测记录到的地震震相进行初步分析,结果表明,通过测震宽频带记录到的体应变地震波更为精确,震相清晰。建议条件许可的情况下在钻孔应变观测中使用测震宽频带数采提高采样率,以积累体应变地震波的准确资料,为今后的研究工作服务。

| Abstract: | The seismic phases recorded by concurrent observation of body strain with normal digitizer and broadband digitizer from 2009 to 2010 are analyzed preliminarily in this paper. The results indicate that the body-strain seismic waves recorded by broadband digitizer are more precise and their phases are clearer than that of the normal. It suggests that it＇s better to use broadband digitizer with higher sampling rate to record body strain for getting more accurate data of body-strain seismic waves for study in the future. |
