集合是同学们进入高中学习的第一个数学概念,也是数学中的基本概念,在集合的学习过程中,许多同学对空集这个特殊集合的理解往往不是很深刻,尤其在一些解题过程中,由于对空集的不理解,经常会漏掉空集这种特殊情况,从而导致错误.本文主要是探究在实际解题过程中为何漏掉空集的情况,以及在实际解题过程中应该注意哪些问题,从而避免犯同样的错误. The collection is the first mathematical concept that students enter into high school and is also the basic concept in mathematics. During the learning process of collection, many students often do not understand the special collection of empty sets. Especially in some problems solving process , Because of the empty set do not understand, often missed empty set this special circumstances, leading to errors.This paper is mainly to explore why the actual problem-solving process omitted empty set situation, and in the actual process of solving problems should Pay attention to what problems, so as to avoid making the same mistake.
