注意到集合问题的表现形式、思路分析、解题过程往往不同于初中阶段常见的计算题、证明题、化简题, 那么解集合题有没有什么规律可循呢? 集合的唯一要素是元素,因而集合问题的解决,主要靠分析、确定其元素来完成．元素是解决一切集合问题的核心,因此抓住集合的元素进行分析,是解决问题的基本途径． It is noticed that the manifestation, thought analysis and problem solving process of set problems are often different from the common calculation problems, probative problems, and simplification problems in the junior middle school stage. So are there any rules for solving the set of problems? The only elements of the set are the elements, Therefore, the solution of the set problem is mainly accomplished by analyzing and determining its elements. The element is the core of solving all collection problems, so seizing the elements of the collection for analysis is the basic way to solve the problem.
