| 摘 要： | 行列式是代数学习和应用中重要的一个基本内容,而Cramer法则是行列式的压轴,该法则的原始证明要利用和逆用展开法则,复杂且难于理解.本文利用行列式的性质给出Cramer法则的简洁证明,并且根据教材的编排不同再给出了Cramer法则的另外两种证明方法.

| Abstract: | The determinant is a basic and important content of algebra , and Cramer rule is the most important of determinant . The original proof of the rule is complex and difficult to understand with using expansion rule . This paper uses properties of determinant to proof the Cramer rule simple , and gives other two prove methods to Cramer rule according to different textbooks . |
