摘要 利用初等微分学比较了单参数平均与对数和指数平均的几何组合,发现了使得双向不等式Jp(a,b)<Iα(a,b)L1-α(a,b)<Jq(a,b)对α∈(0,(17^(1/2)-3)/2]和所有a,b>0且a≠b成立的p的最大值和q的最小值,其中Jp(a,b),L(a,b)和I(a,b)分别表示a与b的p-次单参数平均、对数平均和指数平均. We compare the one-parameter mean with the geometric combination of logarithmic and identric means by use of the elementary differential calculus,and find the greatest value p=p(α) and the smallest value q=q(α) such that the double inequality Jp(a,b)〈 Iα(a,b)L1-α(a,b)〈 Jq(a,b) holds for α∈(0,(17-(1/2)-3)/2] and all a,b〉0 with a≠b,where Jp(a,b),L(a,b) and I(a,b) denote the p-th one-parameter,logarithmic,and identric means of a and b,respectively.
