摘要 利用指数平均与对数平均的基本性质,证明了指数平均与对数平均的几何平均与Seiffert平均的大小关系,得到的结果改进了一些已知的不等式. This paper shows the quantitative relationship between the geometric average of identric mean and logarithmic mean and the Seiffert's mean by means of the basic properties of identric mean and logarithmic mean.This result improves some well-know inequalities.
