但是，由于行列式中的元素通常是符号化的，即其中每个元素都是关于变元（或参数）的多项式，导致行列式展开时的中间计算过程膨胀（甚至爆炸）。

However, as each entry in the determinant is symbolic, that is, a polynomial in variable(s), this leads to the intermediate expression swell(or explosion) problem in the expansion of determinant.

在现行《线性代数》教材中，关于行列式按行(列)展开法则推论的证明，基本上采用同一种方法。

It is always in the same way in proving the inference of the rule that determinant spread in row or column in the current "Linear Algebra" teaching material.
