有限差分正演模拟 声波 高阶 包含边界条件 震源方程-finite difference code with boundary condition and source function

本实验应用声波方程作为正演模拟的波动方程，将所提供震源函数离散后绘图，并将给定两个二维速度 -深度模型，绘出图形。(In this experiment, we use the acoustic equation as the wave equation of forward modeling, draw the source function and draw it, and give two two-dimensional velocity depth models to draw the
