Ker(σ)、Im(σ)与线性方程组解的结构

ABOUTker(σ)、Im(σ)AND STRUCTURE OF SOLUTION OF SYSTEM OF LIEAR EQUATIONS

对Ｋｅｒ（σ）、Ｉｍ（σ）与线性方程组解的结构作了系统的讨论。

In this paper,  ker (σ)、 Im (σ) and the structure of solution of the system of linear equations are systematically discussed and the close relation of the three is expounded.
