Gaussian beam method is essentially a seismic forward modeling method that combines wave equation and ray theory.
高斯射线束方法是将波动方程和射线理论相结合的一种地震正演模型方法。
2
Gaussian beam is the asymptotic solution of wave equation concentred at the central ray.
高斯束是波动方程在特定射线附近的高频渐近解。

Having adopted the quadratic approximation of potential, we can solve the equation and get the approximately analytical solutions of Gaussian typed breath mode.
