摘　　要：利用凹函数和半正定矩阵的性质,讨论并且得到了一些矩阵Rotfel型范数不等式.另外,通过研究Hermitian矩阵和斜Hermitian矩阵和的特征值的模行列式的不等式,得到一些关于Hermitian矩阵和斜Hermitian矩阵和的范数不等式.推广了文献中的相关结果.With the character of concave function and semi-positive definite matrices, some new results of norm inequality related to Rotfel＇ s, trace inequality for some concave functions and arbitrary matrix were given. In addition, through studying the Hermitian matrix and skew Hermitian matrix and the characteristic value of the mode of the determinant inequality are Hermitian matrix and get some about the Hermitian matrix and unitarily invariant norms. The paper generalizes the result in the literature.
