摘要

对分层格林函数在空间域上的渐近展开进行了检验，并提出了通过确定一个小参数推导出三层和四层结构格林函数的简化形式的参数化方法。为了对同一层测量点和源点的精确格林函数和渐近缩短格林函数进行定性测试和比较，我们进行了数值计算。

ASYMPTOTIC ANALYSIS OF ACOUSTIC GREEN’S FUNCTIONS

An asymptotic expansion of layered Green’s function is examination in a spatial domain and parametric approach is proposed by determining a small parameter to derive the shortened form of Green’s function for 3- and 4-layered structures. For qualitative testing and comparison of the exact Green’s function and asymptotic shortened Green’s functions associated with the measurement and source point in the same layer, we performed numerical calculations.
