| 摘 要： | 本文介绍了流体饱和的多孔媒质中声波传播特性,较详细地讨论了声波从各向同性固体入射到多孔媒质界面时反射波、折射波势函数与入射波势函数的振幅比,计算了各种波所携带的声功率在入射波声功率中所占比例.本文的数值计算虽然限於高频,但所提出的方法可应用於任何频率的声波.

| Abstract: | The sound wave propagation in fluid-saturated porous media is described and the reflection and refraction of sound waves at an interface between solid and fluid-saturated porous media are discussed in more detail. The relative amplitudes and power partitionings for reflected and refracted waves are calculated. The method given in the paper may be extended to any frequencies of sound waves, although the numerical calculation here is correct for higher frequencies. |
