平面图的

Part two, three and four have made conclusions and evolutions about the circular chromatic number of planar graphs, Mycielski graphs and distance graphs.

第二、三、四部分分别总结了关于平面图、Mycielski图和距离图的圈色数的一些结论和这些问题的进展情况。

The second part points out the weakness in the planar graph of Heawood's counter example and also its types by GR graph. It also offers a new type of counter example so as to replace the former one.

第二部分通过GR图对希伍德反例进行了深入的探讨，指出该类型的平面图自身有破绽并给出新的反例类型以取代原反例。

This great property is in a good condition and with excellent floor plan.

这优良的房屋是在良好的条件和有良好的平面图。

For floor plan layout, the structures' position on ichnography was determined according the functional requirements for the structure and the topography of the sewage treatment plants.

作平面布置时，要根据各构筑物的功能要求和污水厂的地形条件，确定它们在平面图上的位置。

Methods of recording and mapping of ichnography of engineering geology and methods of making the vector and computer mapping of various initial data surveyed in different ways are introduced,horizontal base level of rock being taken as an example.

文中以岩质水平建基面为例，介绍了工程地质平面图图幅的编录测绘成图方法和利用不同方法测绘的各类初始数据进行矢量化计算机成图的方法。

The author built all information concerned the work of graduate management on the campus ichnography, and combine spatial date with attribute date to make the manipulation more convenience.

系统的体系结构设计的基本思想是以图为基础，在校园平面图上建立与研究生管理工作有关的各种信息，将空间数据、属性数据管理相结合，使系统操作更加方便、管理能力得到增强。

The subject introduces the development history and main function of project management software. Then it presents all kinds of management technology concerning to project management software. It discusses emphatically the Microsoft Project, Guanglianda construction budget computer system, construction project bid and tender book making and management computer system, construction project network play making software, constructing ichnography making software and so on

本课程从工程管理软件系统的发展，工程管理软件系统的主要功能以及工程管理软件系统中涉及到的各类管理技术开始，重点讲授Microsoft Project，广联达工程概预算软件系统，工程项目投标标书制作与管理软件系统，工程项目网络计划编制软件，施工平面图制作软件等。

The project will be strict build the material such as ichnography according to the round river make imperial palace for short stays away from the capital that from museum of the Imperial Palace, national library and China archives of the first history checks, restore its in the round treating together, the historical former appearance between Guan......

工程将严格按照从故宫博物院、国家图书馆和中国第一历史档案馆查到的团河行宫建筑平面图等资料，全面恢复其在同治、光绪年间的历史原貌，填补中国皇家文化中的"行宫文化"空白。无法恢复。。。。。。

The result showed , the two dimensional image accumulated by photon emission at some hours. The spontaneous luminescence could be measured by means of photon counting and imaging acquisition. The luminescence intensity of root and leaf was different at the same plane image. It showed that PIAS could objectively display the spontaneous ultraweak photon, and this results provided experimental basis for resea...

结果表明，自发光子长时间积累可形成二维图象；光子计数和采集图象均可得到植物体的自发发光；通过实验探测到幼苗的根、叶在同一平面图象有不同的发光表现；光子成像系统可客观地比较生物自发超弱发光，为进一步研究超弱发光机理提供实验基础。

It is well known that every triangle-free plane graph is 3-colorable.

我们知道一个著名的定理：不含3-圈的平面图是3-可着色的。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
