摘要

台站地震观测中,有时会记录到在同一个近震中多个不确定震相与清楚震相并存的波形,这就需要在多个不确定近震震相中分辨出准确的震相。与《中国地区深度0.0 km近震走时表》中的理论震相到时差进行比较,两者到时差相似,说明假设的震相定位准确。
In the seismic station observation,sometimes waveform where several indiscernible seismic phases coexist with clear seismic phases is recorded in the same near earthquake,which requires us to identify the exact seismic phase among a number of indiscernible near earthquake phases.Assume an indiscernible seismic phase to be working,calculate the arrival time difference between it and a certain clear seismic phase in the same near earthquake seismogram using calculation program,and compare the result with the theoretical arrival time difference in " Near Earthquake Travel Time Table for the Regions of China(0.0 km depth)",if the arrival time difference of two are similar,it indicates that the assumed seismic phase positioning is accurate.
