1) almost separable
几乎可分
1.
We introduce almost secord countable space dlmost first count-able, almost separable spaces and almost Lindelof spaces whivh are generalizations of secord countable, first countbale seoparable and Lindelof spaces, respectively.
本文定义了几乎第二可数,几乎第一可数,几乎可分和几乎Lindelof空间,它们分别是第二可数,第一可数,可分和Lindelof空间的一般化,同时还讨论了这四类空间的性质。
2.
almost first—countable,almost separable)iff its underlying space is almost sec- ond countable (resp.
对一类较广泛的ω—并生成格证明了诱导空间是几乎第二可数性(几乎第一可数,几乎可分)的充要条件是底空间具有相应的几乎可数性,因此这种推广是 Lowen 意义下好的推广。
2) cyclically almost resolveble
循环几乎可分解
3) 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.

4) almost additive
几乎可加
1.
In this paper,we consider a TDS with the specification property,and a sequence of almost additive continuous functions,we define the irregular set for it(in the sense of sub-additive ergodic theorem) and show that this irregular set is either empty or carries full almost additive topological pressure.
在本文里,对具有SPECIFICATION性质的拓扑动力系统及几乎可加势函数,我们定义了几乎可加拓扑压,又从次可加遍历定理的角度,定义了几乎可加势函数的不规则集。

几乎分裂
6) almost expandable
几乎可膨胀
1.
