In this paper, we prove the inequality relations of arithemetric mean, logarithmic mean, exponential mean and geometric mean for two positive numbers by using probabilistic method.

本文用概率方法证明了关于两个相异的正数的几何平均、对数平均、指数平均和算术平均的不等式关系。

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。

Thank you. I mean, I know I sort of said it to you, but you're right. It's logarithmic, right?

但你们是正确的，是对数级的,它有这样的效率是因为他每次能把问题减半？
