摘　　要：本文研究了求解算子与右端数据均有扰动的第一类半正定算子方程的动态系统方法．证明了相应的动态系统Cauchy问题的整体解存在且收敛于原算子方程的解．此外,给出了解Cauchy问题的迭代方法并证明了方法的收敛性．The dynamical system method is studied for solving operator equations of the first kind involving positive semi-definite operator with both operator and right-hand non-exact. This method consists of solving a Cauchy problem for a linear operator equation. It is proved that the problem has a global solution whose limit at infinity solves the original equation. Moreover, two convergent iterative processes are presented for the Cauchy problem of the dynamical system.
