摘　　要：　从最基本的奇异矩阵、非奇异矩阵的概念出发,结合n阶方阵的基本性质,分析和总结了矩阵与其伴随矩阵之间的奇异性关系,并证明了其中的几个主要结论,最后通过实例说明了其应用的重要性.The adjoining matrix and its application play a very important part in the matrix theory. According to the basic concepts of fantastic and nonfantastic matrices, combined with the essential nature n order matrix, the fantastic relationship between matrix and its adjoint is summed up with some conclusions proved. At last, some examples are given to ieeustrate the importance of these conclusions.
