| 中文摘要: |
| 流体饱和多孔介质（以下简写为FSPM）中的声波研究，既属于声学范围，又属于地球物理学范围，无论从原理上和应用上都值得深入研究．本文对流行的BIOt理论以及它的发展和应用做一个简要介绍，包括Blot理论和三种体波，声波在FSPM和流体及固体界面上的反射、折射问题，FSPM样品的参数约声学测量以及并中渗透率的声学测量问题。在附录中介绍了流体和框架间的粘性相互作用项和惯性相互作用项，因为在B沁t理论的发展中，这两项是经常讨论的问题。 |
| 英文摘要: |
| The study on acoustic waves in fluid-saturated porous media (FSPM) is re1atedto both acoustics and geophysics. Its principle and applications are worthy of deep.study. A brief review of the current theory by Biot as well as its development andapplications are given in tliis paper, including Biot’s theory with its three kinds ofbulk wave, the reflection and refraction of acoustic waves on the interface betweenFSPM and fluid or solid, the measurements of the parameters of FSPM sample andthe measurments of the permeability in a well. In the appendix we introduced theviscous interaction term and inertial interaction term between the saturating fluid andthe solid frame, which are often discussed in the development of Biot’s theory. |
