本文利用了湖北区域台网短周期地震仪近几年来所记录的18次远震资料,从地震图上分析了Ps震相;利用Ps—P走时差,计算了相应地震台附近地区的地壳厚度,其结果与重力资料反演的结果基本相符. This paper makes use of 18 teleseismic data recorded by Hubei regional station short-period seismographs in recent years, and analyzes the Ps seismic phase from the seismogram. The Ps-P travel time difference is used to calculate the crustal thickness in the vicinity of the corresponding seismic station , The result is basically consistent with the result of gravity data inversion.
