摘　　要：循环行列式是线性代数中一类特殊的行列式,在实际当中也有其重要的应用。给出循环行列式的概念,通过举例的形式给出简单循环行列式的计算方法,即化为上三角形行列式进行计算,且得到此类行列式的计算公式,进而利用n次多项式的根得到一般循环行列式的计算方法。Cyclic determinant is a class of special determinant in the linear algebra, and there are important applications in the actual. Gives the conception of the cyclic determinant, by the way of giving examples, obtains the computing method of the simple cyclic determinant, changes into a triangle on the determinant to calculate. And obtains the computational formula of this class determinant, and makes use of the roots of the polynomial of degree n, obtains the computing method to solve the general cyclic determinant.
