子域精细积分的稳定性分析

Stability Analysis of Subdomain Precise Integration Method

对于偏微分方程半解析法的方程，子域精细积分法［１］，既可利用精细积分数值精度高及带宽小的优点，又是无条件稳定的，本文对其稳定性予以分析。

For the semi-analytical method derived equations from the PDEs. The subdomain precise integra non method[1] takes both the merit of numerical high precision in the subdomain and narrow bandwidth of the matrix,and is always stable. In this paper its stability analysis is proposed.
