摘　　要：探讨基于非相关文献的3阶知识发现闭合式方法的基本原理,设计基于关联关系共现的闭合式方法。通过实例验证开放式发现方法所挖掘出的潜在关联链条,说明基于非相关文献的3阶知识发现闭合式方法可以实际问题为导向,为研究活动提供服务。The paper discusses the basic principle of close - method of the third - order disjoint literature - based knowledge discov- ery, explores the close - method based on correlation co - occurrence. Furthermore, a comparative experiment is shown, a potential rela- tionship from the open - method is tested and verified. It proved that the close - method of third - order disjoint literature - based discov- ery can be specific issue - oriented, and can provide services for the research.
