摘　　要：从巴里坤地震台站记录到的连续地震波形数据（2010-01~2013-12）中截取震中距30°~95°,震级MS≥5.0共计282次远震波形数据。用时间域迭代反褶积方法提取远震P波接收函数,采用H-κ叠加搜索方法反演台站下方的地壳厚度和泊松比,结果表明：巴里坤台站下方的地壳厚度为42.6 km,泊松比值为0.31,这与前人的研究成果基本一致。The paper collects and cuts waveforms of 282 telessismic events of Balikun seismographic station with epicenter distance in the range of 30°-95°and the M_S≥5.0 during January 2010 and December 2013. Then the paper uses the iterative deconvolution method in time domain to extraction receiver function of teleseimic P wave, and uses H-κ stacking method to inverse the crustal thickness and Poisson’s ration of the station. The results show that Balikun seismographic station’s crustal thickness is 42.6 km, and the Poisson’s ration is 0.31,which is consistent with the previous studies
