频散分析，主要是对槽波进行速度分析，以便获取更多的地质信息。-Dispersion analysis, mainly for slot wave velocity analysis, in order to obtain additional geological information.

频散曲线求解，利用matlab进行lamb的求解，结果与数值分析方法相比，误差较小，对试验结果具有重要参考价值。通过仿真试验，结果结果比较好。(To solve the dispersion curve, using o solve the dispersion curve, using matlab to solve lamb, the results compared with the numerical analysis method, the error is small, the te
