摘　　要：建立了全新的集合族空间,讨论了公共元的通有稳定性,得到了闭集族空间上的交运算在Hausdorff拓扑下的上半连续性,并研究了重合点的通有稳定性.A family-of-set space was established, and its common elements＇ generic stability was studied. The upper semi-continuity of operation of sets＇s intersection in family-of-closed-set space was obtained, and the generic stability of coinci-dent pointis was studied.

关 键 词：集合族空间 公共元 重合点
