当点源产生的射线穿过3D横向非均匀各向同性介质时,计算沿该射线的基本波格林函数的零阶射线解时,几何扩散与焦散数的计算是最基本的步骤。本文阐述了一种新的分解方法,即沿可被细分为若干射线段的总射线规定两个递归量。由本方法的结果可见,点源几何扩散因子及总射线的射线焦散线数可分
When a point source-generated ray traverses a 3D transversely inhomogeneous isotropic medium, calculating the geometric diffusion and caustics numbers is the most basic step when calculating the zero-order ray solution along the fundamental Wavelin function of the ray. This article describes a new method of decomposition that specifies two recursive quantities along the total ray that can be subdivided into several ray segments. As can be seen from the results of this method, the point source geometry diffusion factor and the total radiation ray caustics can be divided
