摘要

///The finite difference equations of the seismic wave field are derived detailedly, used improved center-line method to solve the FD equations with large-spare array,and the stability of the method is analyzed. Through the full wave field modeling in 2D elastic media with horizontal and dip interfaces, the characteristics of the full seismic wave field, including surface wave and body wave, can be modeled clearly.
