我们给出了在声学VTI介质中用于建模和逆时偏移的波动方程，这些方程是直接由胡克定律和运动方程推导而来的。由此得到的关于三个质点速度分量和两个独立应力分量的五个一阶微分方程组，除了声学VTI近似本身外没有其他近似，并且能够以一种自然的方式处理可变密度。
We present wave equations for modeling and reverse-time migration in acoustic VTI media, derived directly from Hooke’s law and the equations of motion. The resulting set of five first-order differential equations in the three particle velocity components and two independent stress components involves no approximations apart from the acoustic VTI approximation itself and allows handling variable density in a natural way.
