摘要
针对微积分教材关于"无穷小的积是否是无穷小"的命题的模糊叙述,证明"一致有界的一族无穷小的积仍是无穷小".
In the textbooks of the calculus and mathematical analysis,the proposition on ＇the product of infinitesimals is an infintesimal＇ is fuzzy, in this paper, a perfect theorem for the product of uniformly bound infinitesimals is infinitesimal and its proof are given.
