文章提出了一种精确计算三维时域格林函数记忆项本身及其导数的方法。基于精细时程方法求解时域格林函数及其导数所满足的定常非齐次常微分方程组,得到时域格林函数数值解。文中通过与解析方法和其他方法的比较,验证了该方法的精确性、稳定性和高效性。

A precise method to evaluate the memory part of the 3D time domain Green function and its derivatives is proposed. Based on the Precise Integration Method （PIM）, the Green Function is ob-tained by solving a steady, non-homogeneous ordinary differential equations. The accuracy, stability and efficient of this method were demonstrated by its comparison with the analytical solution and other method.
