中文摘要：

文献[1]给出了结论：如果n阶方阵A的每一行（列）所有元素之和均相等,则A的伴随矩阵A＊的每一行（列）所有元素之和也相等.给出了新的证明方法,并在此证明方法的基础上讨论了它的逆命题.

英文摘要：

Let A be an n×n-matrix.A＊ stands for its adjoint matrix.It was proved in [1] that,if the sum of all entries on each row（column）of A is equal to each other,then it is also so for A＊.A new proof of the above result was given,and studied the inverse proposition of it on base of the idea of this new proof.
