【Abstract】 On the basis of the research of compactness and paracompactness,this paper puts focus on establishing the separation properties between compact and compact,compact set and closed subset,strong compact set and paracompact set,paracompact set and closed subset.The conceptions of pseudo-formal,sub-formal,hypo-pseudo-formal and sub-hypo-pseudo-formal are given.In addition,some of their properties are discussed and a new definition of completely regular space is given.更多还原
