摘要: 尝试用垂直分量P波接收函数技术，分离莫霍面多次反射透射震相PpPmp，以此确定台阵下方的地壳厚度．利用兰州小孔径台阵记录的16次深远地震资料，分离了PpPmp震相，根据其到时计算台阵下方的地壳厚度约(51.6plusmn;1.8) km，与前人研究结果一致．

Abstract: The vertical-component P-wave receiver function technique is used to extract the Moho multiples (PpPmp phase) and determine thickness of the crust beneath the Lanzhou Seismic Array. The multiples (PpPmp phase) are determined with waveforms from 16 teleseismic deep earthquakes, and then the average crust thickness is estimated, which value is about (51.6plusmn;1.8) km. This result is also consistent with the result of previous studies.
