摘　　要：极限是微积分学的基础,是《数学分析》与《高等数学》教学中的难点之一。在本文我们利用格理论中序极限的定义,为ε-N型定义与同学们对数列极限的直观认识之间建立一座桥梁,使同学们对数列极限概念有进一步的认识。Limit is the basis of calculus, and one of the difficult points in mathematical analysis and higher mathematics. In this paper, vie the the definition of order limit in lattice theory, we build a bridge between the ＂ε-N＂description and the intuitive impression of students on the definition of hmit, which give students a brand new idea about the definition.

关 键 词：下确界 数列极限 ε-N型定义
