离散拓扑 meaning in English

discrete space
discrete topology

Topological optimization for frame of a heavy special vehicle
重型专用车车架的离散拓扑优化
We consider the following periodic boundary valve problems ( pbvps ) : where ( i . e . , f is continuous as a map from the topological space i + r2 into the topological space r ( of course the topology on i , will be the discrete topology )
考虑下面的周期边值问题( pbvps ) ：其中( f是从拓扑空间i r ~ 2到拓扑空间r (这里的拓扑是离散拓扑)的连续映射)
In chapter 5 we introduce the concepts of topological reflexivity in several topologies , namely , the discrete , the norm , the strong and the weak operator topology . we prove that the spaces of ( , ) - derivations on certain operator algebras are topologi - cally reflexive in the weak operator topology . the automorphisms and ( , ) - derivations of reflexive algebras in banach spaces are also characterized in this chapter
在第五章中我们引进了在离散拓扑、范数拓扑、强算子拓扑和弱算子拓扑下的拓扑自反性，证明了某些算子代数上( ， ) ?导子空间在弱算子拓扑下是拓扑自反性的，同时我们还刻画了自反代数的自同构和( ， ) ?导子。
