本文将对该网络的构成、拓扑特征和特性作详细的分析，并着重讨论一种称之为扩展收缩s W格树网络的性能。
In this paper their construction and topological characteristics are studied, and the performance of a class of SW banyans called expanding and contracting SW banyans is discussed in more detail.
本文不利用收缩方法，直接证明了：当图G至多差一边有两棵边不相交的生成树时，G是超欧拉图或者G有割边。
In this note, no using the contraction method, we prove that if a graph G is one edge short of having two edge-disjoint spanning trees, then G has a cut edge or G is supereulerian.
在脲醛树酯中加入其它高分子材料，降低其脆性和收缩性，提高其耐水性。
Macromolecule materials are added into urea formaldehyde resin to decrease its brittleness and contractility, and increase its water resistance.
