色数

In the fifth chapter, we shall determine the adjacent vertex distinguishing incidence chromatic number of two types of join-graph.

在第五章中我们将确定两类联图的邻点可区别关联色数。

The problem of strong-distinguishable fullcoloring at the adjacent vertex of Cartesian product Pn×Pm of the path was discussed.

讨论路的笛卡尔积的邻点可区别的全染色问题，给出路的笛卡尔积Pn×Pm的邻点强可区别的全色数为χast=5 n=2，m≥2或m=n=36 min{n，m}≥3且m+n

The concepts of adjacent vertex distinguishing incidence coloring and the adjacent vertex distinguishing incidence coloring number of graphs are defined on the basis of the concept of incidence coloring of graphs.

在图的关联着色概念的基础上定义了图的邻点可区别关联着色及邻点可区别关联色数，研究了圈、完全二部图、Cm。

In the fourth chapter, we shall determine the adjacent vertex distinguishing incidence chromatic number of complete bipartite graphs, C_m,·F_n graphs and one type ofθ- graph.

在第四章中我们将确定完全二部图、C_m·F_n图及一类θ-图的邻点可区别关联色数。

So far, just have the adjacent vertex distinguishing total chromatic number of graphs such as path, cycle, tree, complete graphs, etc.

由于这种染色有一定难度，目前涉及到的文献极少，仅知路、圈、树、完全图等几类图的邻点可区别全色数。

We shall determine the adjacent vertex distinguishing incidence chromatic number of paths, cycles, stars, fans, wheels, complete graphs.

我们将确定路、圈、星、扇、轮、完全图的邻点可区别关联色数。

Let G be a double-outer plane graph, V, E, F be the set of points, edge and face, a plane graph G is k-total colorable, if the elements of V E can be colored with K-colors, any two distinct adjacent or incident elements receive different colors.

设G是一个双外平面图，V，E，F分别为双外平面图G的点集，边集和面集。G的全色数X是使得V∪E中的任意两个相邻或相关联的元素间均染不同颜色的最少颜色数。

If G is acyclically L-list colorable for any list assignment with |L|≥κfor all v∈V,then G is acyclicallyκ-choosable.The acyclic list chromatic number,denoted byχ_a~l,of a graph G is the smallest integerκsuch that G is acyclicallyκ-choosable.

若对满足|L|≥κ，v∈V的色列表L，G都是无圈L-可染的，那么称G是无圈κ-可选择的。G的无圈列表色数χ_a~l是使得G是无圈κ-可选择的最小的非负整数κ。

Auxiliry operations the following main factors dangersous chromatic number, in each of the 印张 auxiliry tag (overprinter marks, crop and fold marks, a book in a manner worthy of the fold, registration marks, color separation line, in a manner worthy of the book mark, identification number), the control bar (across the entire width of 印张-cards and membership cards to make the control bars, non-business card printing and membership card making part of the exposure control area), and so on.

补助性工序成不合次给包含印弛每不背的色数、补助性标志(套印标志、裁切标志、折叠标志、书帖折标、套准标志、书帖线、色版标志、标志号码)、把持条(不竖跨印弛合座宽度的制卡和会员卡制息把持条、否制卡和会员卡制息部位上的晒版把持区)等。

In 2006,LIU Xin-sheng et al.introduced the concept of star-edge coloring of graphs, a star-edge coloring of graph G is a proper edge coloring of G such that any path of length 4 in G is not bicolored.The star chromatic index of G,denoted byχ_s,is the smallest integer k for which G admits a star-edge coloring with k colors.

2006年，刘信生等提出了星边染色的概念，若图G的一个正常边染色满足G中没有长为4的路是2-边染色的，则称此染色是G的一个星边染色，使得G有星边染色的最小颜色数称为星边色数，记作χ_s。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
