Furthermore we expand it to the case for strongly locally finite semigroup, and prove the following theorem: if \%T\% is strongly locally finite with order function \%f\% and all e\%φ\+\{-1\}\%, where e∈\%T\% is idempotent, are strongly local.
并把它推广到强局部有限半群的情况,证明了如果T是强局部有限半群,有阶函数f,且对每个幂等元e∈T,e-1是强局部有限的,有同一个阶函数g,则S是强局部有限的,且有一个从f和g可算的阶函数。

First,the concept of strong α-locally finite family is introduced in L-fuzzy topologi-cal spaces,and sheaf paracompactness,which more extensive than Ⅱ- paracompactness,is defined,and its basic properties are discu ssed.
首先，在Ｌ－ｆｕｚｚｙ拓扑空间中引入了强α－局部有限族，并以此定义了比Ⅱ型强仿紧性￣［２］更为广泛的层仿紧性，且讨论了层仿紧集的基本性质。

The notion of base-countably paracompact space is introduced and some of its equivalent characterizations are obtained:(i)X is a base-countably paracompact space if there exsists an open basis B for X with |B|=ω(X) such that every countably open cover U={Ui}i∈N of X has a locally finite countabe refinement B′ by members of B,B′={Bi}i∈N and BiUi.
引入了基-可数仿紧空间的概念,给出基-可数仿紧空间的一些等价刻画,获得以下结果:(i)X是基-可数仿紧空间当且仅当存在X的一开基B,|B|=ω(X),对于X的每一可数开覆盖U={Ui}i∈N,都存在B′B,使得B′={Bi}i∈N是U的局部有限的可数开加细,且BiUi;(ii)设X是正规空间,X是基-可数仿紧空间当且仅当存在的一开基B,|B|=ω(X),使得X的每一可数开覆盖都存在由B中的元构成的局部有限的收缩。

Author mainly proves following:(1)X is a Base-paracompact space iff X is a Base-countably paracompact space and every open cover of X has a σ-locally finite open refinement by members of the basis which witnesses Base-countably paracompact space.
主要证明了如下结果:(1)X是基-仿紧空间当且仅当X是基-可数仿紧空间,并且X的每一开覆盖都存在满足X是基-可数仿紧空间的开基的元构成的σ-局部有限的开加细。

By using the concept of the ω-remote neighborhood,some characterizations of the ω-local finite properties,ω-local finite properties and strong ω-local finite properties,such as strong ω-local finite properties ω*-local finite properties ω-local finite properties are given.
利用LF保序算子空间的ω-远域等概念,引进了LF保序算子空间的ω-局部有限性质、ω*-局部有限性质及强ω-局部有限性质等概念,系统讨论了这些概念的特征性质,得到强ω-局部有限性ω*-局部有限性ω-局部有限性。

局部有限群
locally finite group
局部有限群【】叨uy五‘teg心甲;.Ka月研。幼邢，翻rPynna] 每一有限生成子群皆有限的群.任意局部有限群是一个扭群(见周期群(详石浏c脚uP))，但反之未必成立(见R川亩山问题(Burnside prob七m)).一个局部有限群被另一局部有限群的扩张仍是局部有限群.满足子群(甚至是Abel子群)的极小条件的每个局部有限群均包含一个指数有限的Abel子群(【3」)(见具有有限性条件的群(gro叩俪tha血址n郎co画-tion)).一个其Abel子群具有有限秩(见群的秩(扭瓜of ag心tlP))的局部有限群本身亦具有有限秩，且包含一个有限指数的局部可解子群(见局部可解群(1.llysol姐ble grouP)).
