流体饱和多孔隙垂向非均匀固体的弹性波传播理论

建立含有可压缩粘滞流体的多孔隙垂向非均匀弹性固体内之应力波传播理论。论述了其中的一个问题。即当Ｐｏｉｓｅｕｉｌｌｅ流动假设成立的低频率范围且流体与固体的质量密度可相比拟（例如含水饱和岩石之类）时，流体与固体间虽有相对运动但无摩擦的情形。在一定的近似条件下，可以存在两类膨胀波和一类旋转波，它们都存在频散

^THE THEORY OF ELASTIC WAVE TRANSMISSION IN VERTICAL NON-UNIFORM SOLID WITH FLUID SATURATED POROUS LAYER

The authors of this paper proposed a stress wave transmission theory in porous vertical non-uniform elastic solid with compressible viscous fluid. We dealt with one of the problems, in the low frequency range when poiscuille fluid is hylpothesis. right . and the mass density of fluid and solid are comparable (such as wa- ter-bearing saturated rocks), or although there is relative motion but no friction. lt shows that there are two kind of expansion waves and one kind of rotation wave in cer- tain approximate condition. They all have scatter of frequency.
