设n是正整数,a3(n)表示不小于n的最小立方部分,b3(n)表示不超过n的最大立方部分。用初等方法研究了数列a3(n)和b3(n)的渐近性质,给出了关于这两个数列的两个有趣的渐近公式。
Let n be a positive integer,a3(n)be the smallest cube greater than or equal to n,and b3(n)be the largest cube less than or equal to n.The main purpose of this paper is using the elementary and analytic methods to study the arithmetical properties of these two sequences and give two interesting mean value formulas for them.
