用平面上一条封闭的曲线所围成的图形来表示集合,这个图形就叫做韦恩图.集合中图形语言具有直观形象的特点,将集合问题图形化,利用集合韦恩图的直观性,可以深刻理解集合有关概念、运算公式,有助于显示集合间的关系,所以,韦恩图是进行集合运算的有力工具.解题时,若能借助于 The collection is represented by a graph surrounded by a closed curve on the plane. This graph is called the Wayne diagram. The graphical language in the collection has the characteristics of an intuitive image. It graphically sets the problem and uses the intuitiveness of the collection of Wayne diagrams. A deep understanding of the concept of collections and the formulas for calculations helps to show the relationship between collections. Therefore, Wayne maps are powerful tools for performing set operations. If you can solve problems,
