平面图的

This is the floor plan of this apartment/house.

In this paper we discuss the circular chromatic number of planar graphs, Mycielski graphs and distance graphs.

本文研究了平面图、Mycielski图和距离图这三类特殊图的圈色数。

Yap proved that the planar graph with maximum degree △≥ 13 is equitably m—colorable for any m ≥△.

Yap和Zhang[10]证明了：最大度Δ≥13的任意平面图G，对任意整数m≥Δ，都存在均匀m-染色。

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。

Planar graphs also play an important role in colouring problems;to motivate such problems,let us return to our"road-map"graph,and let us suppose that Shell,Esso,B.

平面图在着色问题中还起着重要的作用；为了生动地说明这一问题，让我们回到路线图，并假定Shell、Esso、B。

The following are included in the system: GIS client editing tools; use of the VBA editing environment in the ARCINFO platform; functions custom designed to meet customer needs; and use of the ARCSDE and ARCIMS tools in ARCGIS to manage data space in the E-map and provide to the internet. We have developed a module, using ichnography that is used in the system browser to manage microwave station information visually.

系统中与图形有关的设计和实现包括：GIS客户化编辑工具，我们主要采用了ARCINFO自带的VBA编辑环境，重新按照客户需求定制了自己的功能；使用ARCGIS中的ARCSDE和ARCIMS提供的工具对电子地图空间数据管理和互联网上发布；系统微波站图形方式浏览和管理，我们自己开发了一个模块，利用平面图作为页面的母层，平面图上需要表现的设备、维护人员等传输资源建立子层链接，通过链接可以浏览详细信息。

In the same way, a Four-coloring of a maximal planar graph of 25 order G(subscript M25), is obtained with "simplified method of reduction of order".

利用"简化降阶法"对一个一定拓扑结构的12阶最大平面图G(下标 M12)进行着色，得到G(下标 M12)的四色着色方案；以同样的方法对一个一定拓扑结构的25阶最大平面图G(下标 M25)进行着色，得到了G(下标 M25)的四色着色方案。

In Chapter 2, we show that Xi 3 for all planar graphs of girth not less than 4 which contains no 5- and 6-circuits or contains no 7- and 8-circuits or contains no 8- and 9-circuits, we also show that Xi 3 for each planar graph of girth not less than 4 which contains no 6-, 7- and 9-circuits.

在第二章，论文证明了每个围长至少为4且不含5-圈和6-圈或7-圈和8-圈或8-圈和9-圈的平面图是3-可选色的。同时还证明了每个围长至少为4且不含6-圈，7-圈和9-圈的平面图是3-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。

The main task of the designing is to use CAD to work out a two-dimensional figure on the base of a thorough comprehension of the three softwares, and to use 3Ds max to transfer the plane picture and form a three-dimensional model, completing the drawing of a tridimensional model involving quality and light. Then use Photoshop to do some modify for the picture.

设计的主要任务是在熟悉三种软件的基础上，利用利用CAD绘制居室及家具的二维平面图；使用3DS max导入平面图进行三维建模，完成立体效果图的绘制，包括材质、灯光渲染的制作；最后用Photoshop对效果图进行修饰加工。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
