您要查找的是不是：
- regular closed subset 正则闭子集
- To be precise, if you embed a compact Hausdorff space K in an arbitrary Hausdorff space X, then K will always be a closed subset of X;the "surrounding space" does not matter here. 精确地说，将紧致的豪斯多夫空间 K 放在任意豪斯多夫空间 X 中，K 总是 X 的一个闭合子集；
- Let X be a metric continuum and let 2(superscript X) and C (X) denote the hyperspaces of subcontioua and of closed subset of X, respectively, F1(X) is 1-fold symmetric product of X. 摘要给定连续统X,2(上标X),C(X)，分别表示X的闭子集和子连续统的超空间，F1(X)是X的一重对称积空间。
- The main result is as follows: Let X be a regular space, then the nonempty closed subsets hyperspace is locally compact iff X can be represented as the sum of a compact space and a discrete space. 主要结果是：X正则，则其闭子集超空间局部紧当且仅当X可表示成一个紧空间与一个离散空间的拓扑和。
