主要引入了q–正规空间,得到了以下主要结论:(1)X是q-正规空间当且仅当A闭X和A的任何一个开领域U,存在A的一个开领域V,使得V-(q)U;(2)q-正规空间的α-集子空间是q–正规空间等.
主要引入瞭q–正規空間,得到瞭以下主要結論:(1)X是q-正規空間噹且僅噹A閉X和A的任何一箇開領域U,存在A的一箇開領域V,使得V-(q)U;(2)q-正規空間的α-集子空間是q–正規空間等.

In this paper, the notion of q - normal spaces was introduced and the following results were mainly obtained and proved: (1) X is a q -normal space if and only if for every closed setA of X and every open domain U ofA , there is an open domain V, such that - set subspace of q -normal space is q -normal space, and so on.
