3D frequency and space domain amplitude-preserved migration with viscoelastic wave equations;

Finite element parallel algorithm for numerical solution of elastic wave equation;

Based on elastic wave equation, a high-order finite-difference scheme was derived in staggered grid space, and the relation between absorbing boundary conditions and numerical dispersion was also studied to establish the mathematical model of coal multi-component seismic exploration.

In this paper, the medium parameters of the elastic wave equation in inhomogeneous medium are rewritten by introducing the referential Yariables and the perturbational variables, and the wave squation whose sources are the medium paremeter perturbatioal term in homogeneous medium is obtained.
