为了做到这点，必须对地震记录进行相位校正及大地滤波校正。

It is therefore necessary to have the seismic data corrected for phase and earth filtering.

使用相匹配滤波技术提取基阶面波振型的相位，然后再利用时变滤波进行振幅谱校正，以此分离出基阶振型面波信号。

Phase-matched filter is applied to extract phase of fundamental surface wave, and then time-variable filter is used to correct amplitude spectrum in order to isolate fundamental mode signs.

为了有效消除静态效应，提出了一种静态校正新方法——带相位的滑动滤波法，并具体阐述了带相位的滑动滤波法的算法思想。

This paper proposes a new method, moving filtering having phase method, to static correct CSAMT, and elaborates the concept of moving filtering having phase algorithm specifically.
