摘 要 一致連續(xù)性是連續(xù)函數(shù)的一個(gè)非常重要的性質(zhì), 它刻劃出了函數(shù)在一個(gè)區(qū)間上的全局性。冪函數(shù)是一類非常重要的基本初等函數(shù)。對于冪函數(shù)的一致連續(xù)性,我們從幾個(gè)常見例子出發(fā)來探討下它們的一致連續(xù)性問題。本文主要討論冪函數(shù)在區(qū)間(0,+)上的一致連續(xù)性。

Abstract Uniform continuity is a very important property of a continuous function, which sculpts the global nature of the function over an interval. The power function is a very important elementary function. For the consistent continuity of power functions, we start from a few common examples to discuss their uniform continuity problems. This article focuses on the consistent continuity of the power function over the interval.
