屋顶

He built two huts with pimento trees, covered them with long grass, and lined them with the skins of goats, which he killed with his own gun as he wanted, so long as the powder lasted, which was but a pound; and that being almost spent he got fire by rubbing two sticks of pimento wood together upon his knee...

他用甘椒树给自己搭了两个小屋，并用茅草做屋顶，屋顶的边沿是他用火枪打到的山羊的皮做的。在他需要的时候，他会用火枪去打些山羊，但能供他使用的火药也只有一磅的样子，用完了也就没有了。火药现在已经用得差不多了，他只好用两根甘椒树的树枝在自己膝盖的摩擦，打出火来。

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。

This paper presents the design for wind-induced vibration control of roof truss, with the calculation results and experiment performance of energy dissipation damper given.

以合景大厦为工程背景，介绍了屋顶构架风振控制设计，并给出了基于弯曲错动耗能的阻尼片的试验性能分析及屋顶构架控制的数值计算结果。

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。

It is partly thanks to him, and particularly the Grove, that every new shopping centre built in America next year will be roofless (and several traditional shopping malls will tear off their roofs).

因卡鲁索，更确切地说是格罗夫购物中心，使得第二年在美国每一个新建造的购物中心都是没有屋顶的（一些传统的购物商厦也想把屋顶掀走）。

This is often used on conservatory roofs and is much stronger than corrugated plastic sheeting .

使用聚碳酸酯薄膜为固体屋顶部分，这是经常使用的温室屋顶比波形塑料板更强。

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

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。
