路标

This paper has studied the synthesis of hot-melt road marking paint using modified rosin -alkyd resin.

还研究了路标涂料基料树脂的合成，其中包括改性松香树脂的合成、醇酸树脂低聚物的合成以及改性松香-醇酸树脂的合成。

However, keywords can only represent the simple content, which easily dissever the relevancy of the content The deep-content representation and application are not developed, so semantic navigation is not satisfied at present. Time mechanism is a kind of navigation mechanisms that uses time for the signpost, and determines navigation route according to the time of occurrence.

时序机制指以时间为导航路标、根据事物发生的时间顺序确定访问路径的一种导航机制，主要应用于WWW信息空间中以时问顺序为线索组织信息的结构中；空间机制指依据对象间的空间关联，为用户指引路径，提供导航路标的机制，应用于具有空间特征的结构中；社会机制指利用先行者的经验、建议为后来者指引路径的行为，原来主要应用在推荐系统、协作系统中，目前已经在主流的信息检索系统中得到了应用，如在CNKl知识网络服务平台（CNS 5.0）中的应用。

Containing the Visible Region positioning and the Sequence Region positioning raised in this paper as well as the Orientation Region positioning raised by Levitt [17] , the qualitative positioning method segments the environment of robot into different equivalent classes , and describes the positions without coordinates but just using landmarks and landmark relations, based on the extracted qualitative relations from images such as the visibility of landmarks, the sequence of landmarks and the position relative to the landmark pair boundary .

定性定位包括本文首次提出的可见区域定位和顺序区域定位，以及Levitt[17]提出的有向区域定位，利用通过图像获取的路标的定性关系如路标的可见性，路标排列的顺序和相对于路标对边界的位置等，将机器人的运动环境划分为若干个等价类；其定性性体现在不必使用坐标就可描述机器人的位置，这种定位方法只利用视觉反馈中的定性信息。

By midday they had reached the King's Road, a wide path paved with rough-hewn stone. At the crossroads stood a large wooden sign, inscribed with simple letters.

中午他们到达了国王大道，那是一条用粗糙的岩石铺成的道路，岔道口中央立着木制路标，路标上刻着简单的文字。

And finally she could also replace the signpost so that it correctly named the direction she had come from.

第三种方法是，她可以把路标扶起来，路标会准确地显示她来的方向。

Under the guidance of the road signs, this thesis tries to "restart the beginning" more originally; that is to say, through the expanding and contracting of the Phenomenological horizon "To the things themselves", let these road signs as the beginning of Taoistic immortality belief unbosom itself anew,or be giver again in the depth of "Being" truly.

在这些路标的引导下，本文力图更源始地去"重新开始这个开端"，也就是在"朝向事情本身"的现象学境域的伸缩之中，让这些作为道教神仙信仰之开端的路标，真正在"存在"的深度上重新给予自身，重新吐露自身。

Keep straight on until you see a road sign that says " Central Park ", and then you follow the sign.

一直走就可以看见中央公园的路标，按着路标走，它会带你到那。

First,a landmark model is designed to give position information;second,color segmentation,invariance of cross-ratio and the self-adaptive window are used to detect the artificial landmark,so the position information is got;finally,in order to locate the mobile robot accurately,the binocular stereo vision is used by combining with the position information of artificial landmark.

首先设计了一种可扩展的彩色人工路标，并给出路标的编码方法；然后利用色彩空间变换，直线交比不变性以及自适应窗口实现路标检测与识别；最后在分析双目立体视觉模型的基础上建立起基于路标的双目立体视觉定位模型，实现移动机器人的准确定位。

With no road signs and few maps, they had to put their trust in directions passed by word of mouth and in secret signsnails driven into trees, for example-that conductors used to mark the route north.

没有路标，地图也很少，他们只好相信别人给他们所指路的方向以及自己辨认那些钉在树上的暗号：例如，通常过往的向导都会留下向北的路标暗号。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
