本文对多孔弹性体中观察到毕奥慢纵波的超声实验进行了数值模拟。模拟使用OASES建模代码，它允许计算弹性波场在层状多孔弹性介质。模拟的是Plona（1980）、Rasolofosaon（1988）的实验和我们自己的测量。在所有三种情况下，实验和模拟之间的良好协议已被观察到。这进一步证实了这样一个事实，即模拟所基于的毕奥多孔弹性理论充分描述了在超声频率下研究的多孔材料的行为。
We perform numerical simulation of ultrasonic experiments on poroelastic samples, in which Biot's slow compressional wave had been observed. The simulation is performed using OASES modeling code, which allows to compute elastic wave fields in layered poroelastic media. Modeled were the experiments of Plona (1980), Rasolofosaon (1988), and our own measurements. In all the three situations, a good agreement between experiment and simulations has been observed. This further confirms the fact that Biot's theory of poroelasticity, on which the simulations were based, adequately describes the behavior of the porous materials under investigations at ultrasonic frequencies.
