This paper presents a survey on the properties and distributions of contractible edges and removable edges in 3 connected graphs.
综述了3连通图中可缩边和可去边的性质以及它们在图中的分布情形。
An edge of a 6 connected graph is said to be 6-contractible if its contraction results still in a 6 connected graph.
如果6连通图的一条边收缩后使得所得到的图仍是6连通，则这条边称为6可收缩边。
Contractible edges and removable edges in connected graphs are a powerful tool to study the structures of connected graphs and to prove some properties of connected graphs by induction.
图的可收缩边与可去边是研究连通图的构造和使用归纳法证明连通图的一些性质的有力工具。
The paper discusses the far-field condition and analyzes the outcomes of a contractible-scaled test. The result shows that this method is simple, convenient and credible.
文章讨论了测试的远场条件，并对一个具体的缩比测试实验的结果进行分析，结果表明：该方法简便易行，数据可信。
In this paper a concept of contractible closed set is introduced in H-spaceand a generalized KKM theorem (Theorem 1)which is parallel with C-KKM theorem isobtained.
在H-空间中引入了可缩闭集的概念，得到了一个与C-KKM定理相平行的广义KKM定理。
