- Discuss about the countability of set of real numbers and the relevant problems
的可数性及其相关问题 - By the method of " every open set in r " is the union of an at most countable collection of disjoint connected open sets " , the paper deals with some problems of countability in real analysis
摘要以“平面上互不相交的若干开集所成之族至多可数”为基点，对一些相关结果给出了全新的直观化证明。 - However the other is abandoning the countability and strengthening the " order " , i . e . , replacing the space r in insertion theorem by complete chains ( connected complete chains ) and gain a series of good results also
另一个方向相对于第一个方向去掉了可数性，加强了序，即文[ 4 ]中讨论的内容：用完备链(连通完备链)代替插入定理中的实数空间r 。 - A number of properties of countable topological space were given systematically , such as its countability , separability , compactness and connectedness , including their proofs on the basis of the nature of topological space , real number space and corresponding theorems
摘要在可数补拓扑空间的拓扑性质的研究基础上，系统的给出了可数补拓扑空间的可数性，分离性，紧致性，连通性等性质，并给予证明。 - This theorem have been generalized in many ways . there are mostly two aspects in them , one is replacing the space r in insertion theorem by completely distributive lattices with some countability , i . e . , liu and luo in [ 6 ] try to use lower ( upper ) semicontinuous map well defined to define the normality of fuzzy topol ogical space and gain a series of good results [ 6 ]
这一定理已经被以多种形式推广，其中主要有两个方向，一个是用具有某种可数性的完全分配格来代替插入定理中的实数空间r ，即刘应明和罗懋康在他们合写的文[ 6 ]中就尝试在格上定义模糊拓扑空间的正规性，并得到了一系列很好的结果。
