1) almost first countable
几乎第一可数
2) almost second countable
几乎第二可数
3) almost countabilities
几乎可数性
1.
In this paper,we prove that almost quasi-Lindelf property can be preserved by almost homeomorphism mapping,and study the relation between the LF almost countabilities with the LF countabilities in a semiregular space.
本文讨论了几乎准Lindel f性质在映射作用下的某些性质和LF几乎可数性与LF可数性在半正则空间中的关系。
4) almost countable paracom pactness
几乎可数仿紧
5) almost countable sheaf paracompactn
几乎可数层仿紧
1.
By the base of almost countable F-compactness,sheaf paracompact hess and countable paracompactness in L-Fuzzy topological space,in this artical,counta ble sheaf paracompactness,almost countable paracompactness and almost countable sheaf paracompactness are investigated.
本文以L—Fuzzy拓扑空间中的几乎可数F紧性、层仿紧性以及可数仿紧性为基础,研究了L—Fuzzy拓扑空间中的可数层仿紧性、几乎可数仿紧性以及几乎可数层仿紧性。
6) nearly reducible
几乎可约
1.
In this paper we make research on the set NK of indices of convergence and the set NH n of indices of maximum density for the class of n×n symmetric imprimitive nearly reducible Boolean matrices.
本文完全确定出n(>2)阶对称非本原几乎可约布尔矩阵的幂敛指数集和最大密度指数集。
补充资料:第一可数公理
第一可数公理
first axkm of countaUity
第一可数公理【丘谧.匆以口成。翔..目甸;uep的.aK-饮。Ma四哪ocT,] 集论拓扑中的一个概念.拓扑空间称为满足第一可数公理(fnsta幻Drn ofco四tabiljty),如果每个点的定义邻域系都有可数基.满足第一可数公理的空间类是F.比。面叮(1914)定义的.所有的度量空间,线段上的连续函数空间等都属于这个类.满足第二可数公理(s以刀nd~of courltab正ty)的空间也满足第一可数公理.反之不然,例如具有离散拓扑的不可数空间不满足第二可数公理. M.1.Bo如exo鱿班j撰胡师度、白苏华译
