本文讨论了各向同性非均匀介质中运动方程近似为标量波动方程及标量波动方程近似为射线方程(动力学及运动学)的条件,也讨论了这些条件之间的关系,还给出了射线振幅的一个新的数值解法。
In this paper, we discuss the approximation of the equations of motion in isotropic inhomogeneous media and the approximation of the scalar wave equation to the ray equation (kinetics and kinematics). The relationships between these conditions are also discussed. A new numerical solution to the amplitude.
