SH波作用下半圆形凸起地形内波函数的求解
On solution of wave function of semi-cylindrical protruding landscape under SH-wave
【摘要】 采用"分区"的思想,利用复变函数和傅氏展开的方法提出了求解SH波作用下半圆形凸起地形内波函数的一种方法,给出了满足半圆形凸起地形边界条件的波函数形式,从而为进一步讨论凸起地形对SH波的散射问题奠定基础。
【Abstract】 By adopting the"division"thought,the paper making use of the complex function and Fourier opening method,points out an approach for the solution of wave function of semi-cylindrical protruding landscape under SH-wave,and provides the wave function form which can meet the border landscape with semi-cylindrical protruding condition,in order to lay basement for the further discussion about the scattering problems of the protruding landscape on SH-wave.
