Using pattern recognition, we can obtain the slowness, amplitude andprimary frequency of compressional, shear and Stonely waves respectively, andthen calculate the available geological parameters.

我们根据各波型到达时间、相位、振幅和频率四方面的差异进行模式识别，在离散化输入条件下从长源距全波波形图上分离提取了纵波。横波和斯通利波的时差、振幅和主频，进而计算出各有关地质参数。

With density of cracks/fractures increasing,the delay time of fast and slow shear wave increases.

因此，瞬时主频和快横波的偏振以及延迟时间可以作为裂隙方位和密度的指示。
