说明：  基于频散曲线，选择抽样脉冲信号作为子波，推导出了合成单炮面波地震记录的理 论公式，并利用该公式，针对不同弹性层状介质模型的频散曲线合成了面波地震记录。
(Based on the dispersion curve, select the sampling pulse signal wavelet derived synthetic single artillery surface wave seismogram theoretical formulas, and the use of the formula, seismogram synthesis of surface wave dispersion curves for different elastic layered media model.)
