| 摘 要： | 在点集拓扑理论中,开集、邻域等是最基本的概念。现行的点集拓扑教材中,只讨论了积空间X=X1×X2…×Xn与Xi关于拓扑基,拓扑的子基的关系,本文继续讨论X与Xi关于领域、闭集、闭包、内部、边界、局部基、局部子基的关系。

| Abstract: | In point set topological theory, open set and neighborhood are the basic concept. The current point set topological text - book only discusses the relationship of product space with topological base & subba-se. This paper continues to discuss the relationship between neighborhood, close set, closure, interior, border , local base and local subbase. |
