摘要
定义高次方程的正项分解 ,对高次方程在作正项分解后所揭示出的一些性质加以讨论 ,以期有助于高次方程的数值解法 .
In this paper, we give a definition of the resolution on positive terms for equation of higher degree. We also discuss a series of problems appeared with the resolution, in order to conduce to the n umerical solution method for equation of higher degree.
