摘　　要：为了使用户快速的对感兴趣的概念进行搜索,提出了一种等价关系约束属性的概念分析方法。给出了属性间等价的定义并讨论了相应的性质,在此基础上通过属性等价约束关系得到了一种格结构理论,并处理了它们之间的一些性质。通过一个实际例子,说明了此方法的现实意义。In order to quickly search the interest concepts for usersi,t provides an analysis way for formal concept analysis of attributes constrained by equivalent relation.It first gives a definition between attributes constrained by equivalent relations,and discusses some relative properties.Afterword,based on the above resultf,or the concept constrained by the equivalent rela-tionst,he construction of them in lattice theory is obtained.In additions,ome properties of this construction are dealed with.Fi-nallya,real example shows its significance in real life.
