A simple discriminance on the matrix of rational number field Q to cycle matrix

有理数域Q上的矩阵为周期矩阵的一种简易判别法

Some common results which used to decide a polynomial on rational number field irreducible are explained in this paper.

首先介绍了判别有理数域上多项式不可约的常用结论,讨论了形如f(x)=φ(x)(x-a1)(x-a2)…(x-an)+1的多项式的性质,并且得到了定理:若n>6,φ(x)>0且它的次数小于n的一半,则f(x)=φ(x)(x-a1)(x-a2)…(x-an)+1在Q上不可约。

By indirectly applying the Eisenstein discriminant method,this paper explores and discusses two ways of judging the integral coefficients polynomials to be irreducible over the rational number field.

探讨了间接应用艾森斯坦因判别法判断整系数多项式在有理数域上不可约的两种途径。

In field of circuit theory, the conclusion about structure properties of electrical network based on the field of real number is determined by both network structure and the value of element, but structure properties based on the field of rational functions in multi-parameters is only determined by network structure and not by the value of elements (because these elements do not have values).

在电路理论领域内,关于电网络结构性质的研究都是基于实数域上的(描述系统的状态方程系数矩阵都在实数域上),得到的有关网络性质的结论由网络的结构和网络中元件的取值共同决定,但是基于多元有理函数域F(z)上的研究方法所获得的网络的性质只由网络的结构决定而与网络中元件的取值无关(因为这些元件都没有取值),只需观察网络的结构即可知道网络是否能控能观,方法直观简便,特别适合电网络的分析与综合。
