摘　　要：运用可拓工程理论中物元的共轭对概念对知识集合进行分析,提出知识集合的显隐、正负、虚实、软硬四个概念以及知识集合中要素的显隐、正负、虚实、软硬四种表现方式,分别从图书馆实际工作出发,通过实例详细阐述基于共轭对知识集合的显隐、正负、虚实、软硬性质在图书馆文献资源建设与图书馆文献信息服务中的初步应用。The concept of the conjugated characters in Extension Set Theory is used to analyze the knowledge set in four aspects such as the explicit and the implicit, the positive and the negative, the actual and the virtual, the hard and the soft, the paper demonstrates the preliminary application of these four characters＇ in library resource construction and information service through several practical examples.
