摘要
以河南洛阳基准地震台数字观测记录的地震波形为基础,总结了震中距6°～20°的影区地震的震相特征,对台站一线观测人员在震相的准确判别及提高地震定位精度方面具有实际的指导意义。
Based on digital seismic waveform records at Luoyang, Henan Reference Seismological Station, seismic phase characteristics of shadow zone for earthquakes with epicenter distance of 60-200 km are analyzed. It has practical significance for observation personnel of the station to distinguish seismic phases correctly and to improve precision of earthquake determination.
