摘要
由于台站周围环境噪声干扰的增强,台站人员无法识别被背景噪声淹没的初至P波。我们利用DIMAS分析软件包中的谱分析方法,寻找初至P波的卓越周期,改善台站人员识别地震波的能力。
Owing to strengthening of environment noise interference around seismic station, the P arriver is hard to be recognized. We use spectral analysis method, provided by the DIMAS analysis software package, to find the outstanding period of P first arriver and improve the capacity for recognizing seismic waves.
