The two - parameters weighted mean in defined and an inequality for two - parameters weighted mean of convex function is prove, they have generalized and improved the results in literatures.
Besides, a new inequality on generalized logarithmic mean is obtained.
此外,还得到关于广义对数平均的一个新的不等式。

In this paper, we introduce a new concept of generalized derivative, and derive its operational rules and the mean value theorem of continuous functions.
