Based on the characteristics of wavelet transform, the wavelet Singularity Detection is used to locate the feature point and anomaly extension of the Rayleigh wave dispersion curve.
基于小波变换原理，利用小波分析中的奇异性检测方法来对瑞利波频散曲线的特征点和波动区段定位。

Especially in the rural market, the majority of the geographical dispersionof the population, the need to take a few very good point spread.
尤其是农村市场，地域广大人口分散，就更需要很好的把握几个传播交点。

The occurrence of zero walk off point can efficiently restrain the first_order polarization mode dispersion.
