本文主要是介绍Java实现二维VTI介质一阶拟声波方程正演模拟GUI图形用户界面（加强版），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
依据的拟声波公式如下：
du/dt=1/rho*dp/dx ,
dw/dt=1/rho*dq/dz ,
dp/dt=rho*vpx^2*du/dx+rho*vp*vpn*dw/dz ,
dq/dt=rho*vp*vpn*du/dx+rho*vp^2*dw/dz ,vpx^2=vp^2*(1+2*epsilon);vpn^2=vp^2*(1+2*delta);import java.awt.event.ActionEvent;
