Examples
- Theorem 20 is the basis of a rather detailed study of the structure of extremal graphs .
定理20是极图构造更详细的研究的基础。 - In the third section , we get the extremal graph of weighted graph whose connectivity is 2
在第三节中得到连通度为2的赋权图在ore型条件下的极图 - Then g contains a y - longest path p ( x0 , y ) such that d ( x0 ) if g has one . we discuss the structure of graph satisfying the conditions in theorem a and give the extremal graph
… y ）满足d （ oo ）三号我们对满足超a条件的图的结构进行了讨论，给出了m极图 - Combination of this lemma and the hamilton - connectivity involving neighborhood intersection obtains and improves or generalizes a series of classical results involving hamilton - connectivity , at the same time , we construct some extremal graphs to show the improved results to be the best possible ones . as for hamiltonicity , we omit the similar discussion
由于每一个偶阶哈密尔顿连通图是o -因子-临界的，我们在最后一章中我们主要涉及哈密尔顿连通性，利用一个重要的引理，我们得到了一些新结果，并且改进了或推广了一些经典结论。 - The first section of this paper gives a brief introduction about the basic concepts , terminology and symboles which are used in this paper . in section 2 , we give an accurate discussion about the structure of a kind of graphs in [ 6 ] and get the extremal graph . in the third section , we introduce a new concept - - - - implicit weighted degree and using it we give a condition on the existence of heavy cycles in weighted graphs
在本文的第一部分中，我们简要介绍了论文中所涉及的一些概念，术语和符号；在第二部分中，我们对中图的结构进行了精确的讨论，给出了一个极图；在第三部分，我们定义了一个新参数?隐赋权度，给出了赋权图中重圈存在的隐赋权度条件；最后，在第四部分，我们给出了赋权图中过两点的重圈存在性的dirac型条件。
