查询词典 choosable

This implies that bipartite graph G is (G/2 + 1-choosable.

从而，可得每个二部图G是可选的。

Therefore, we have to consider a weak problem, that is, toclassify the (2,3)-choosable complete bipartite graphs.

事实上，这是一项困难的工怍即使是对3一可选的完全二部图，也是如此。

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。

In addition, we prove that every planar graph without 4-circuits and intersecting triangles is (3, l)*-choosable.

此外，论文还证明了每个无4-圈和相交三角形的平面图是(3，1)~*-可选色的。

In Chapter 3,we obtain that:(1)each planar graph without 4-cycles is acyclically 6-choosable;(2)each planar graph without 4-cycles and without triangles at dis-tance less than 3 is acyclically 5-choosable.

在第三章中，我们获得了以下两个结果：(1)每个不包含4-圈的平面图是无圈6-可选择的；(2)每个不包含4-圈并且任意两个三角形之间的距离至少是3的平面图是无圈5-可选择的。

Used the way of discharging to prove that every planar graph without 4-cycles and i-cycles for some i ∈{5,6,7} is (3, l)*-choosable, when they studied the list improper colorings of plane graphs.

72在研究平面图的列表非正常染色时，结合欧拉公式用放电的方法证明了每个不含4-圈和i-圈的平面图是(3，1)~*-可选的，其中i∈{5，6，7}。

Header or footer can be specified with choosable font and size and with optional page number.

页眉或页脚，可以指定可选的字体和大小和可选的页码。

Header or footer can be specified with choosable font and size and with optional page number.

页眉或页脚可以指定可选的字体和大小与可选页码。

Thus the (2,3)-choosable completebipartite graphs are completely characterized here, which, we consider, will beIIuseful in the further research of the 3-choosable bipartite graphs.

我们给出了所有的(2，3)一可选的完全二部图，星图、(m+n≤9且当n一4时m≠5)，相信此结果对研究3一可选二部图会有一定帮助。

Total of 240 choosable cases including 120 males and 120 females with HCT parameters 0.42L/L and 270 choosable cases including 150 males and 120 females with HCT parameter 0.45L/L,examined by pressure transfer type viscometer from healthy testers.

结果不论是锥板式还是压力传感式血流变仪的测定结果，各相同HCT组的高、中、低切全血粘度值按不同性别比较均无显著性差异（P＞0.05）。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。
