| 摘 要： | 目前多数线性代数教材中关于线性方程组的克莱姆法则的证明都要用到代数余子式概念和行列式展开定理．而利用分块矩阵知识，很好的改进了文献3]的证明方法，得到克莱姆法则的一种更加简捷的证明．

| Abstract: | In almost every introductory book on linear algebra, the proofs of Cramer's Ruler are familiar with the cofactor of a determinant or expansion theorem of a determinant. a better, simple and new proof that im-proved methods of proof than literature of 3] is given to Cramer' s Rule on linear equations by partitioned matrix. |
