摘要
本文导出了联系任意对称的各向异性固体层上下界面力学量（位移和应力）的传递矩阵，从而提出了层状固体媒质声反射和声透射的一般模型，作为例子，本文数值计算了金属铝中双层正交对称固体（其间界面呈刚性联接或滑移联接）对声波的反射和透射系数。
In this paper, we have derived the transfer matrix for a general anisotopic layer and proposed a generalized model for sound renection and transmission on layered anisotropic media. As an example, we have made numerical computations of sound reflection and transmission coefficients on two orthotropic layers in isotropic aluminum with rigid or slip interfaces
