| 摘 要： | In this paper, a concept of the β-property of symmetric matrices is presented which is useful in the perturbation theory for matrices. A necessary and sufficient condition for a symmetric matrix to have the β-property, and the constant β,when it exists, are given. Further, the scaling stability of the symmetric matrix which has the β-property is investigated.
