【摘要】 稳定性是数值计算波动方程的最重要条件之一．本文就正交对称和六方对称各向异性介质中的弹性波动方程研究了时间和空间上差分精度可达任意阶的交错网格高阶差分法后，又导出了该方法的稳定性条件．为利用这种既精确又高效的数值方法来研究地震各向异性中的正反演问题提供了理论依据．更多还原

【Abstract】 Stability is one of the most important conditions in which we numerically solve the wave equations.Using the elastic wave equations in orthorhombic and hexagonal media we have studied the staggered-grid high-order difference method,whose accuracy be arbitrarily in time and space,and deduced the stability conditions of the method.Hence,we have established the basis of applying this accruate-efficient numerical method to forward and inversion problems in seismic anisotropy.更多还原
