摘要
本文指出行列式的元素有数值和下标(行标和列标)两个要素。行列式的许多定理实际上描述了行列式的值与两要素的关系。并指出:在一些定理的证明中,突出行列式元素的两个要素,可使证明思路清晰,简单明了,容易理解。
The article points out that any element of a determinant consist of two key factors: the numerical value and the subscripts (row subscript and column subscript). In fact, many theorems about the determinants describes a relation between the value of the determinant and the two key factors. In addition, in the proofs of some theorems, to emphasize the two key factors of elements of a determinant makes the proofs simpler and easier.
