In the article,a one parameter and a two parameter family of generalized mean values were defined,their basic properties and monotonicities were investigated,the function q(t;x,y)=∫ y xf(u)u t-1 d u, where f(u) is a nonnegative and continuous function,was researched.
本文定义了广义平均的单参数簇和双参数簇,研究了它们的单调性等基本性质,还研究了函数∫yxf(u)ut- 1 du 的性
