摘要: 给出可测集中点的密度的简单性质;推广一元近似连续函数到多元情形,得到可测函数与近似连续函数之间的关系。

关键词: 可测集, 密度, 可测函数, 近似连续函数, n维空间

Abstract: The simple properties of the density of the points in measurable sets are given. The author generalizes one element approximately continuous function to multivariate case,and the relations between the measurable functions and the approximate continuous functions are obtained.

Key words: measurable set, density, measurable function, approximate continuous function, n dimensional space
