So far , mathematicians who study topology have obtained substantial achievements in important topological directions , such as generalized metric space , cardinal function , compactness , dimension theory , etc . but what is worth to paying attention to is that we often draw on one special type of topological space to think and solve problems , for example , the classical structures , sorgenfrey line k , michael line rq , niemytzki planetv , kxk , # q xp , etc . ; subtle and profound topological properties aredetailedly characterized by them 而值得注意的是,在一般拓?fù)鋵W(xué)的研究歷史中,我們常常借助一類特殊的空間來思考和解決問題,如我們熟悉的經(jīng)典構(gòu)造: sorgenfrey直線k 、 michael直線r _ q 、 niemytzki平面n 、 k k 、 r _ q p等等,漂亮地刻畫了細(xì)微而深奧的拓?fù)湫再|(zhì)。
