摘　　要：针对知识化制造系统自重构后的新知识网合理性问题,研究了知识网的内在结构机理。首先利用等价关系对知识点集进行分类,构造知识点集的功能拓扑空间;通过真集建立知识点集和功能拓扑空间之间的联系;给出关于功能拓扑空间的基的相关结论,阐述了知识网、拓扑空间和基在本质上的对应关系。在明确这种结构原理的基础上,提出利用等价关系、基和基本知识点对知识网进行约简,利用传递闭包研究知识网复合联系的完备性,从而简化知识网的结构并增强知识网的合理性。最后,通过实例说明了该理论的有效性。Aiming at the rationality of new knowledge mesh, which was obtained from the self-reconfiguration of knowledge-oriented manufacturing systems, the inherent structure principles of the knowledge mesh was studied. Firstly, the sets of the knowledge points were classified by the equivalent relationships, and the function topological space was constructed. Relationships between the sets of the knowledge points and the function topological space were established by the real set. In the function topological space, the base-related conclusions were presented, which indicated the essential mapping relationships of the knowledge mesh, topological space and base. After knowing the principles of mapping relationships, structure of the knowledge mesh was simplified by using the equivalent relationship, the base and the basic knowledge points. Completeness of the complex relationships in the knowledge mesh was studied by the transitive closure. These conclusions could simplify the structure and enhance the rationality of the knowledge mesh. Finally, the given example revealed that these theories were effective.
