利用-型特征值包含定理及修正矩阵，给出随机矩阵两个新的非1特征值包含区域，并由此得到随机矩阵非奇异的两个新的充分条件。数值例子表明，在某些情况下所得结果改进了几个已有结果。 Two new inclusion regions of eigenvalue different from 1 of stochastic matrices are given by using the -eigenvalue inclusion theorem and the theory of modified matrices; and two new sufficient conditions of stochastic matrices nonsingular are obtained. Numerical examples are given to show that the existing results are improved in some cases.
