摘要
｛２｝——逆近年来才开始引起学术界广泛的关注．虽然已有不少的工作，但多是在一定背景下讨论的，而关于其本身的研究甚少．本文主要对｛２｝——逆相应于传统广义逆的表征作了一些研究，它具有一些独特的性质，最后考虑了若干分块阵的｛２｝——逆．
In recent years, {2}—inverse causes more concerns gradually in academic exchanges. Although many researches have been carried on it, they are most done under certain background, few researches are about {2}—inverse itself. In this paper, we will mainly discuss the expression about {2}—inverse in contrast with {1}—inverse, the special properties and the {2}—inverse of partitioned matrix.
