本文从自由空间中的并矢Green函数出发，引入了一种构造平面分层均匀媒质的并关Green函数的新方法。根据平面分层均匀媒质中不同取向的点源辐射在场声、处的响应得到了并失Green函数的港分量．再由谱分量得出了平面分层均匀煤质并关Green函数的积分表达式。 Starting from the dyadic Green’s function in free space, this paper introduces a new method of constructing a parallel-off Green’s function for a flat layered homogeneous medium. According to the point source radiation with different orientation in the flat layered homogeneous medium, the response of the point source is obtained and the port component of Green function is obtained. From the spectral components, we obtain the integral expression of the uniform stratified coal and the Green function.
