| 摘 要： | 详细讨论了远震体波SV分量接收函数的特点及其在反演地壳S波速度结构中的优势．与径向接收函数类似，SV分量接收函数可通过对远震体波的SV分量直接反褶积P分量获得．研究分析表明:与径向接收函数相比，SV分量接收函数的振幅随震中距的变化更加稳定，波形简单且突出了对结构最敏感的PS转换波信息．理论数值实验显示:在反演地壳S波速度结构时，SV分量接收函数比径向接收函数具有更好的收敛性．作为实例，利用SV分量接收函数反演方法反演了海拉尔台下的S波速度结构．

| Abstract: | In this article, we analyze the character of SV-component receiver function of teleseismic body waves and its advantage in mapping the S-wave velocity structure of crust in detail. Similar to radial receiver function, SV-component receiver function can be obtained by directly deconvolving the P-component from the SV-component of teleseismic recordings. Our analyses indicate that the change of amplitude of SV-component receiver function vs. the change of the epicentral distance is less than that of radial receiver function. Moreover, the waveform of SV-component receiver function is simpler than the radial receiver function and gives prominence to the PS converted phases that are the most sensitive to the shear wave velocity structure in the inversion. The synthetic tests show that the convergence of SV-component receiver function inversion is faster than that of the radial receiver function inversion. As an example, we investigate the S-wave velocity structure beneath HIA station by using the SV-component receiver function inversion method. |
