太原基准地震台震相分析在数字地震观测中的应用

Application of Seismic Phase Analysis to Digital Earthquake Observation of Taiyuan Reference Seismological Station

以太原基准地震台数字观测记录的地震波形为基础,对不同类型地震所出现的震相从到时、周期、先后次序等方面进行了对比分析,对台站一线的观测人员在震相的准确判别,提高地震定位精度方面,有实际的指导意义。

Based on the digital seismic waves recorded in the Taiyuan Reference Seismic Station, the seismic phases of different types of earthquakes are comparatively analyzed on aspects of arrival time, periods and arrival orders. This work is practically meaningful to guide observation staff of the station to analyze seismic phases more accurately and improve earthquake location precision.
