实数集R的不同拓扑结构和拓扑性质

The Different Topological Structures and Topological Property In Real Number Set

针对实数空间R中不同的拓扑结构,讨论实数空间R若干拓扑结构之间的关系,并讨论在不同的拓扑结构中,聚点、极限点等有关性质。

Through comparing the different topological structures in real number space the author, finds some relatives among many topological structures in real number space and draws related properties of accumulation point and limit point in different topological structures.
