用接收函数研究地壳各向异性,首先要提取高质量的接收函数,然后计算接收函数Ps震相的分裂或拟合Ps震相随后方位角的变化特性来提取地壳的各向异性参数。在提取接收函数的方法中,频率域方法简单,执行效率高;时间域方法精度高、稳定性好。与先前的方法相比,接收函数的各向异性研究针对整个地壳,对于更准确地分析地壳结构、了解壳幔耦合关系、岩石圈形变及动力学特征具有重要的意义。作为研究各向异性的方法之一,接收函数的各向异性研究仍然在发展之中,会有更广阔的发展前景。
To study the crustal anisotropy by using the receiver function, we first extract the high-quality receiver function, and then extract the crustal anisotropy parameters by calculating the azimuth of the splitting or fitting Ps phase of the receiving function Ps. In the method of extracting the receiving function, the frequency domain method is simple and the execution efficiency is high. The time domain method has high precision and good stability. Compared with the previous method, the anisotropy of receiver function is studied for the whole crust. It is of great significance to understand crustal-mantle interaction, lithospheric deformation and dynamic characteristics more accurately. As one of the methods to study the anisotropy, the anisotropy of the receiver function is still under development and will have a broader development prospect.
