teleseismic events

The P-wave travel time residuals of 300 teleseismic events at 50 stations in East China ( 100 °-125 ° E, 20 °-45 ° N) were studied in this paper.

本文研究了300个远震事件在中国东部（100°125°E，20°45°N）近50个台站的P波到时残差。

On the basis of the observation data of Beijing Telemetered Seismic Network, the parameters of 66 teleseismic events are calculated once again by using program TEL 92. The results are analysed and compared with PDE. Some enlightening conclusions are obtained.
