viscoelastic medium

Probing the medium with a time harmonic homogeneous plane wave gives the Christoffel equation. Then the complex velocities for homogeneous viscoelastic waves are calculated from it, while the attenuation factor and phase velocity and quality factor are obtained from the complex velocity.

The classical elasticity mathematics theory was established for ideal medium abiding Hooke law grimly, the earth medium is a viscoelastic medium with viscosity in fact, so elastic wave equation can not be used to describe the propagation of seismic waves in real media.

经典弹性数学理论是对精确遵守虎克定律的理想介质建立的，而实际大地介质是具有粘滞性的粘弹性介质，所以完全弹性波动方程不能够准确地描述地震波在实际介质中的传播过程。
