摘要
从集合论的等价关系出发，论述了集合论与等价的关系，探讨了分类的基本思想，以同构为例单述分类在数学发展中的地位和作用，并说明它在几何学中的发展和应用．
Based upon the equivalent relation in set theory, this paper presents basic thoughts of classification. Taking isomorphism for example, it also presents classification's position and effect in development of mathematics and explains its evolution and application in geometry.
