This paper offers a pleasing paean to the Chinese special way of progress in perspectives of the economic growth, socialist modernization, increasing global influence and international reputation, the steady and stable realization of the transformation of economic and political systems.

中国道路"是中国特色社会主义现代化的道路，是使中国融入世界和参与经济全球化进程的道路，是以发展经济为中心并且以渐进、增量、积累的方式使经济政治体制的改革实现软着陆的道路。这是一条成功的道路，史无前例。"

This approach uses the geometric features and radiation features of the road, according to the small amount seed points given by the user, each point in the road centerline can be gotten. Then an adaptive gray template is used to adjust each point in the road centerline. Finally, least square method and Newton iteration method are adapted to each point in the road centerline to fit a polygonal line.

该方法利用道路地物的几何特征和辐射特征，根据用户提供的少量道路种子点，利用自适应灰度模板对道路中心线上的每个点进行调整，最后采用最小二乘算法和牛顿迭代法对调整后的道路中心线上的每个点进行拟合，以此获得趋近于道路中心线的最佳折线。

In this paper ,we utilize the imagery with greater 1 meter resolution which is so called very high resolution as experimental data and do the research of ribbon road and simple building roof , and we talk about the process and method of extraction from high-resolution remotely sensed imagery :the representation of road and building in high-resolution image is analyzed ;a method of semi-automatic extraction for ribbon road based on angular texture signature and profile matching is promoted ;a algorithm for road extraction based on Snakes model is compared and analyzed ;the method of object-oriented image analysis and classification is introduced and we utilize this method to extract simple building roof semi-automatically ;the algorithm of road extraction is implemented as prototype system ;finally , the practicability of above-mentioned method are evaluated .

本文以分辨率大于1米的超高分辨率遥感影像作为试验数据，以具有一定宽度的带状道路和简单建筑物屋顶作为研究对象，探讨分析了高分辨率遥感影像中地物要素的半自动提取过程和方法：分析了高分辨率遥感影像中道路和建筑物的特征表现；提出了一种基于角度纹理特征和剖面匹配的带状道路半自动提取方法；对比分析了基于Snakes模型的道路提取算法；介绍了面向对象的图像分析和分类方法，使用该方法对简单建筑物屋顶进行了半自动提取；以原型系统方式对道路提取算法进行了实现；最后结合试验，对上述各种方法在实用性方面进行了评估。

Can think that road traffic safe program is government and its function department is , make the personal casualties of road traffic accident lose with property in program issue fall to the goal intended, determine in the traffic safe measure and action and its enforcement that person, vehicle, road and environment should adopt with the aspects such as management sequential, it is different levels people's government and its function department science develop the road traffic at will sexual major basis and important means of blindness of working and preventing road traffic safely working decision safely , it is strategy and the direction of road traffic safe development, have the scientificness of guaranteeing road traffic safe management and avoid decision fault before Zhan sexual role, have important strategic meaning for preventing road traffic accident.

可以认为，道路交通安全规划是政府及其职能部门为使道路交通事故的人员伤亡和财产损失在规划期内降至预定的目标，确定的在人、车、路、环境和管理等方面应采取的交通安全措施和行动及其实施时序，是各级人民政府及其职能部门科学开展道路交通安全工作、防止道路交通安全工作决策的随意性和盲目性的主要依据和重要手段，是道路交通安全发展的方向与战略，具有保证道路交通安全管理的科学性及避免决策失误的前瞻性作用，对预防道路交通事故具有重要的战略意义。

The experiment is began with the runoff quality on the diverse roofage and different grade roadway, the results are as follows:(1) The concentration of contamination is different with the diverse roofage, and SS value is also different with the style roof;(2) In the beginning , the concentration of COD value and SS value is higher ,but the runoff quality will be reduced to steady gradually along with the rainfall duration increase;(3) The city roadway runoff is worse than the roadway of university ,because the city roadway runoff involve vehicle n people and the sanitation and material of roadway;(4) Based on the analysis of rainwater quality , the paper provide the process of rainwater treatment for roof, roadway, and lawn.

对教学区内不同建筑物，及道路上的雨水径流水质进行监测，得出以下结论：(1)材料不同，径流雨水中污染物浓度不同，屋顶类型不同，径流雨水中SS浓度亦不同；(2)初期径流污染物浓度很高，随降雨历时的延长，COD和SS浓度逐渐下降并趋于稳定；(3)道路污染与路面材料、来往车辆、人员流动、路面卫生状况有关。市区道路相比校园内道路，水质较差；(4)对雨水水质分析基础上，分别对建筑屋顶、道路、绿地提出雨水利用的处理工艺。

Secondly, according to the related standards of city planning, different standards roads are divided into five grades with different driving speed, which are expressway, trunk road, secondary truck road, branch road and subway. Considering the general situation of Beijing traffic, in this model the minimum value of designed speed is evaluated to each road that in different grade.

然后根据城市规划的相关标准，将不同标准道路分为快速路、主干道、次干道、支路和地铁等5个等级，不同等级的道路赋予不同的行驶速度，考虑北京道路交通的一般状况，模型中各等级道路均取设计速度的最小值，对没有道路覆盖的区域，按照实际情况赋予15km/h的通行速度（表1）。

It was not wet yet cold and dark and flooded a road This road is digesting the old one You can hear the sound of gravel, cement and water wagon tracks which the wind wasn't quick enough to smooth away a corpse frozen by snow, and a car leaving with happy songs The most faithful year, or two years its biggest sore is that it's not been hurt The molds on the road are home for magpies In the distance, the sea overflows by itself like people who live outside life vaguely derailing Time will make them very poor and prove that great pique can be disaster to them, though that's not happened yet I've walked along this road, it was once occupied by grass and dirty snow Where there's now a lamp post, I used to loiter.

它不是湿的却是冷而黑的将一条道路淹没这条道路，正在消化着原来的道路你会听到一些沙石的声音，一些水泥和水风来不及吹走的车辙一块积雪冻僵的尸体，还有一辆汽车满载快乐而去的歌声最忠诚的一年，或两年它最大的伤害是没有受到伤害道路上的霉斑，是喜鹊的家园远处的海水空自泛滥那只是生活以外之人一次不着边际的出轨时间会让它们一贫如洗并证明巨大的怨气于他们是灾难，但没有发出来我走过的这条道路，曾被青草或肮脏的雪们占领落脚之地如今站立着灯柱。

This is not an ordinary box, which is used as a background picture of the dialog box, very pretty.

详细说明：这可不是一个一般的对话框，它是用图片作为背景的对话框，非常好看。

Conceal me what I am,and be my aid for such disguise as haply shall become the form of my intent.

遮掩我的身份，帮助我，我的面具将成为我的目的。
