在较弱的扰动条件下，研究了闭线性算子的广义逆和摩尔{Penrose}逆的扰动及其表达式.作为应用，我们还研究了闭EP算子的摩尔{Penrose}逆的扰动.本文得到了一些新的有趣的摄动结果和例子。
We consider the perturbation and expression for the generalized inverse and Moore{Penrose inverse of closed linear operator under a weaker perturbation condition. As a application, we also investigate the perturbation for the Moore{Penrose inverse of closed EP operator. Some new and interest- ing perturbation results and examples are obtained in this paper.
