| 摘 要： | 本利用Ｂｉｏｔ饱和多孔介质动力学理论及饱和多孔介质和固体介质交界面的连续条件，推导了平面ＰＩ波以任意角饱和多孔介质向弹性固体介质入射时，反射快Ｐ１波，慢ＰＨ波和ＳＶ波和透射Ｐ波、ＳＶ波系数的计算公式，并给出一算例，本不考虑饱和多孔介质中液体渗流的能量耗散。

| Abstract: | On the basis of Biot's dynamic theory for liquid-saturated porous solid, in this pa-per, the formulae are deduced for reflecting coefficients and transmitting coefficients on the in-terface between liquid-saturated porous solid and solid while P1 wave is incident at differentangles. The continuous conditions on the interface are used and dissipation of energy is notconsidered when the wave is propagating from the liquid-saturated porous solid medium tothe solid medium. At the end, an exemple is given. |
