应用高阶交错网格有限差分算法，并加入吸收边界条件和衰减带，对弹性波方程进行模拟，分析了其稳定性和收敛性。通过对各向同性和各向异性介质模型的模拟表明，高阶差分波动方程模拟的网格频散较小、精度较高、效果较好，可为地震勘探及其资料解译提供技术手段。

This paper analyzes the stability and convergence of the seismic wave ifeld by using the high-order staggered-grid limited differential method of joining the absorbing boundary condition and attenuating zone to simulate the elastic wave equation. The results of the simulation of both isotropic-and anisotropic-medium models show that the grid frequency dispersion of the high-order differential wave equation simulation is smaller and more accurate. Therefore, this method should improve the efifciency of seismic prospecting and of the associated data interpretation.
