But at present only for some special cases of complete multipartite graphs, Ohba's conjecture have been verified.

容易发现Ohba猜想成立的条件是当且仅当它对完全多部图成立，但是目前只是就某些特殊的完全多部图的图类证明了Ohba猜想的正确性。

Furthermore, author analyzes the properties of the multiplicatively weighted Voronoi diagram and the additively weighted Voronoi diagram and the compoundly weighted Voronoi diagram, and with the aid of GIS software author develops a simple raster-based approach to construct above three weighted Voronoi diagrams.

分析了倍增的、相加的和复合的加权Voronoi图的性质，提出了一种基于GIS的构建加权Voronoi图的简便方法，该方法可以生成两维空间上任意图形的加权Voronoi图，这种方法基本上可以满足城市与区域规划应用研究的需要。

It is shown that every minimum geodetic set of a graph does not contain its cut-vertices, and if G is a block graph with n≥3 vertices and k≥1 cut-vertices,then g=n-k.

图的每个最小测地集都不包括它的割点，如果图G是一个有n≥3个顶点，k≥1个割点的块图，那么g=n-k。

A free edge in a Ramsey graph of K n is defined as whatever does the edge to be colored by one of two colors respectively,the graph will keep to be a Ramsey graph of K n.

在 Ramsey图 Kn中一条自由边定义为，即使单独改变这条边的颜色，所得到的新图仍是一个二色 Ramsey图 Kn 。

This paper proved that the MAXIS algorithm is a 2-approximation to the SC of proper interval graphs with Bounded Degree and α≤ω. where α is the maximum degree of vertices of graph, n is the number of vertices of graph.

本文证明了对一类特殊的真区间图Δ≤(4n~(1/4)且α≤ω，其中Δ是图G中点的最大次，n是图G的点数，α是G的最大独立点集所包含的点数，ω是G的最大团所包含的点数，MAXIS算法是解决其染色和问题的2-近似算法。

In 1997, Lenhard Ng Michelle Schultz[1] gave the definition of k -ordered Hamilton graphs,namely, let G be a Hamiltonian graph of order n,and for a positive integer k with k ≤n, we say that G is k -ordered if for every sequence S : v1 , v2,Λ,vk of k distinct vertices, there exists a hamiltonian cycle C of G such that the vertices of S are encountered on C in the specified order.

年， Lenhard Ng Michelle Schultz[1]给出k-可序( k ？ordered)哈密尔顿图的定义，即设G是n阶哈密尔顿图，对于正整数k，称G 是k -可序图，如果对于任意给定的k 个互不相同的顶点的有序子集S =( v1 ，v2，Λvk)( 2≤k ≤n)，存在G中的哈密尔顿圈C 包含S 且不改变其中元素的顺序。2000 年，R.J。

When is a network diagram for the problem of, or can convert the network diagram problem, can use to illustrate the method to solve.

当给出的问题是一个网络图，或者可以转换成网络图问题时，就可以用图解法来求解。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
