摘　　要：将多项式的根的估计与定位和矩阵特征值的估计与定位联系起来,讨论数论命题中几类特殊的多项式特征根的估计方法,得到一般多项式的特征根的估计方法。The estimation and the localization of the polynomial root were associated with the estimation and localization of the matrix eigenvalues in this paper. The estimation and the localization of polynomial characteristics mot by some special kinds of proposition were discussed, and then the estimation of the general pol- ynomial features root was obtained.

关 键 词：多项式 根 友矩阵 估计与定位
