提出了一种计算流体覆盖的多层弹性半空间声材料特征的理论。固体层由均匀各向同性线弹性材料组成，并在界面处紧密结合。计算过程在任意高频率的激励下都是有效的。给出了两种激励频率下均匀、单层和四层半空间模型的结果；一个中等（35 MHz），另一个相对较高（370 MHz）。指出了材料特征的几个新特征及其在层状试样材料表征中的可能应用。
A theory is presented for the calculation of the acoustic material signature of a multilayered elastic half‐space overlain by a fluid. The solid layers are composed of homogeneous isotropic linearly elastic materials and are firmly bonded at the interfaces. The calculation procedure is valid at an arbitrarily high frequency of excitation. Results are presented for a uniform, a single layered and a four layered model of the half‐space at two frequencies of excitation; one moderate (35 MHz) and the other relatively high (370 MHz). Several new features of the material signatures and their possible use in the material characterization of layered specimen are indicated.
