说明：  建立简单的层状模型，共三层，褶积合成地震记录，使得数据随机缺失30%，分别用傅里叶变换、短时傅里叶变换、s变换、小波变换对地震数据进行时频分析。(A simple layered model with three layers and convolution synthetic seismogram is established. The data are randomly missing by 30%. Time-frequency analysis of seismic data is carried out by Fourier transform, short-time Fourier transform, S transform and wavelet transform, respectively.)
