摘　　要：行列式是线性代数中非常重要的内容,也广泛应用于许多实际问题的解决,它为求解线性方程组问题提供了工具。然而高阶行列式的计算却是这部分的难点,需要根据所求高阶行列式的形式,分析其所具有的特点,采用适当的方法将高阶行列式的计算进行简化。该文将主要针对3种特殊形式的高阶行列式进行分析,从而给出相应的计算方法。Determinant is a very important content in linear algebra,it is widely used to solve many practical problems.It provides a tool for solving linear equations.However,It is difficult to calculate high-order determinant.We need to analyze its characteristics according to the form of higher-order determinant.In this paper,three special forms of high-order determinant are analyzed and the corresponding calculation methods are given.
