摘　　要：定义了集合近似邻域,研究了其基本性质,探讨了各种集合近似邻域的关系,以及集合近似邻域与集合邻域、近似算子、点近似邻域、近似拓扑邻域等的关系.用集合近似邻域为手段,研究了知识论域拓扑空间,得出了一些重要结论.In this paper, a concept of a set approximate neighbourhood is defined. Some basic properties of the concept, relationship among various kinds of set approximate neighbourhoods, connections among set approximate nelghbourhood and set neighbourhood, approximate operators, point approximate neighbourhood, approximate topology neighhourhood, etc, are studied. The knowledge universe topology spaces are studied by set approximate neighbourhood, and many important conclusions are achieved.
