多孔介质的声波

ACOUSTIC WAVES IN POROUS MEDIA

南京大学声学研究所

本文根据M.A.Biot的理论,介绍了多孔介质中三种体波的传播特性和测定这三种波波速的模式转换方法,测量结果表明,理论与实验结果基本一致。文中指出了这项研究对地震勘探、声波测井资料解释有一定意义。

In line with the Biot theory, the propagation properties of three kinds of bo ody waves in porous media and the technigues for mode conversion in meaburing the velocities of these three kinds of body waves were introduced. The measured results are consistent with theory. Also, it is demonstrated that the approach re ecommended in the paper is positively of significance in processing the data collected from seismic survey and well logging.
