摘 要:
波动方程数值模拟是研究地震波传播特征的有效手段。从非均匀弹性各向同性介质中的波动方程出发，研究发展了伪谱法数值模拟方法，并给出了稳定性条件。用该方法对一个实际复杂构造模型进行模拟，得到了较高精度的单炮记录，且波场特征丰富，表明本模拟方法是研究复杂地质构造中地震波传播特征的一种有效方法。[著者文摘]

Abstract:
Numerical simulation from wave equations is a valid means of studying seismic wave propagation, In this paper, the pseudospectral method by the wave equations of inhomogeneous elastic isotropic media is developed and the stable conditions for it are given. This method is used to simulate a real complex structure, the shot records are precisely gained, with abundant wave field features, The case study shows that this method is more suitable for simulation of seismic wave propagation in complex geologic structures.[著者文摘]
