| 摘 要： | 利用接收函数方法对甘肃测震台网下方的一维S波速度进行了研究。结果显示甘肃测震台网各个台站下方地壳内部可分为两层:第一层深度为20~25 km之间;第二层为Moho界面,其平均深度约为50 km,界面上表面的速度约为3.8 km/s,界面底部的速度约为4.5 km/s。

| Abstract: | Using the method of receiver function the S-wave velocity structure under Gansu seismic network is studied.It is concluded from the inversion results that the crust under Gansu seismic network consists of two layers,the depth of the first layer is between 20 km and 25 km; the second interface is Moho,with the average depth of about 50 km.The velocity above this interface is about 3.8 km/s,and on bottom of this interface is about 4.5 km/s. |
