我们得到了均匀孔隙耗散介质中纵波传播的解析瞬时解。基于一般毕奥多孔弹性方程的解适用于低到高频的范围,除了松驰机理外,它还包括一般属性的粘弹性现象。我们利用粘动力学算子在全频率范围内模拟了与孔隙中流体相对运动有关的动力学 We obtain the analytic instantaneous solutions of the longitudinal wave propagation in an even pore dissipative medium. The solutions based on the general Biot’s elasticity equation apply to the low-to-high frequency range and include, in addition to relaxation mechanisms, visco-elastic properties of the general properties. We use the kinematic operator to simulate the dynamics associated with the relative motion of fluids in the pore over the entire frequency range
