讨论了超仿紧性的性质以及超仿紧性与仿紧性的关系 ,得到了超仿紧性是好的推广、闭遗传的。
In this paper, the basic properties of ultra paracompactness and the relations between ultra-paracompactness and paracompactness are discussed.Furthermore,the results that the ultra-paracompactness is hereditary with respect to closed subsets,a weakly topological property ,and a good extension are obtained.
