一类凸函数的Hadamard不等式

A Type of Hadmard Inequality of Convex Function

该文通过引入函数ｆ（ｘ）的下指数的概念，对闭区间［ａ，ｂ］上单调凸函数的Ｈａｄａｍａｒｄ不等式进行了改进，结果比文［２，３］为优。

In this paper, the concept of the lower exponent of function is introduced, the Hadamard inequality of monotone convex function on ciosed interval[a,b] is improveted, these results are more optimal than one in [2] and [3].
