摘要：

For positive real numbers a, b,■. In this note, we generalize this fact to matrices by proving that for positive semidefinite matrices A and B of order n, for any ■, where s;（X） denotes the j-th largest singular value of X and ■.This result sharpens some known result. Meanwhile, some related results are established.
