摘　　要：为识别粘弹性介质的本构模型，建立了线粘弹性的波动方程，并给出了一维问题线粘弹性波的简谐解和识别方法，这在理论和实用上都有重要意义。In order to identify the constitutive model of linear visco-elastic medium, the wave equation of linear visco-elasticity is established. Also,a simple harmonic solution to the linear visco-elastic wave in one dimensional problem is made and a method of identification is presented here.It is fairly significant both in theory and in practice.
