摘要
用不同于普通教学参考书的方法证明了高等代数中的替换定理,并在证明的同时给出了一种实用的替换方法;给出了求两组向量所分别生成的子空间的交的基的方法,并在理论上给出了证明．
The substitution theorem is proved by a new method different from teaching reference books. In the meantime a practical method of substitution is presented. A method to find out the base of intersection of two subspaces is given and proved theoretically, where the subspaces axe generated by two groups of vectors respectively.
