摘　　要：在分明拓扑空间中引入强拟开集和强拟闭集的概念,并讨论了它们的性质.以实例说明它们与开集、强拟半开集等概念之间的强弱关系.In this paper,strong pre-open and strong pre-close sets were introduced in topological spaces and their properties were researched. The relationships of open set, strong pre-semi open set and strong pre-open set were revealed by examples.

关 键 词：拓扑空间 强拟开集 强拟闭集 强拟连续映射
