摘要  设S(n,d)表示由全体迹为d的n阶对称本原矩阵所构成的集合,本文给出了S(n,d)中全体矩阵的本原指数集,并完全刻划了S(n,d)中本原指数达到上界的极矩阵. Suppose that \%S(n,d)\% denote the set of all symmetric primitive matrices with \%d\% trace. In this paper, we give the exponent set of matrices in \%S(n,d)\%. Moreover, the extreme matrices with the largest exponent in \%S(n,d)\% are also characterized.
