If the coefficient matrix of the system of linear algebraic equations is strictly diagonal dominant or irreducible weakly diagonal dominant, the stopping test formulas of the iterative method x(s+1)=Gx(s)+K for solving PDE is proposed in this paper.

• 当线性代数方程组的系数矩阵是严格对角优势或不可约弱对角优势时,本文给出了使用迭代法u~(s+1)=Gu~(s)+K解偏微分方程时的终止检验公式。
