摘要
本文在子域精细积分法的基础上，提出解偏微分方程的任意差分精细积分法，这种方法既具备子域精细积分法的各种优点，还能较好描述非均匀介质的物理特性及灵活处理各类边界条件，且其显式计算格式是无条件稳定的·
Based on the subdomain precise integration method, the arbitrary difference precise integration method (ADPIM) is presented to solve PDEs. While retaining all the merits of the former method, ADPIM further demonstrates advantages such as the abilities of better description of physical properties of inhomogeneous media and convenient treatment of various boundary conditions. The explicit integration schemes derived by ADPIM are proved unconditionally stable.
