摘要
研究了二维横向各向同性介质中关于位移分量u_x,u_y与u_z的偏微分波动方程组进行三分量弹性波场有限差分法模拟的稳定性问题,分别获得了y向分量与x、z向分量正演模拟时所必须满足的稳定性条件,提供了三分量记录数字仿真稳定所需的时空离散间隔约束。
In this paper we have studied the stability problems for 3-componct clastic wavcficld modelling with tinitc difference method in-2-d transverse lylsotropic media and obtained the stability conditions which should be met inthc uy component's and ux,uz component's modelling respectively
