摘要 该文基于一个抽象微分方程的二阶Runge-Kutta方法,构造一种求解线性不适定算子方程的迭代方法——中点法,并讨论此方法的收敛性及收敛速率,数值试验的结果也与该理论相符. This paper proposes an iterative method for solving ill-posed operator equations based on dynamical systems and discuss the convergence properties and convergence rates of the method. Numerical examples are given, which is in agreement with the theoretical results.
