| 摘 要： | 首先基于理论地层模型，分析使用径向切向接收函数集联合反演地壳各向异性程序的可行性和可靠性。然后将该程序应用到余干地震台接收函数的实际分析中，结果显示，不同目标函数计算得到的快波偏振方向和时间延迟存在差异，联合目标函数结果表明，余干地震台快波方向约为79°，时间延迟约为0.19 s。

| Abstract: | First of all, based on the theoretical crustal model, the feasibility and reliability of using the radial and transverse receiver functions to jointly invert the crustal anisotropy program are analyzed. Then the program is applied to the actual analysis of the receiver functions of Yugan seismic station. The results show that the polarization direction and time delay of the fast wave calculated by different objective functions are different. The joint objective function shows that the fast wave direction of Yugan seismic station is about 79° and the time delay is about 0.19 s. |
