几何形状

Finally, the locations of independent buildings were obtained. In the aspect of structure line detection, the main idea is to separate the roof structure lines into two parts, one is for external contours and the other is for internal structure lines. The external contours were extracted using Hough transform and other geometric conditions. The internal structure lines were extracted by any two adjacent roof faces intersecting each other.

而在结构线的侦测方面，主要将屋顶结构线分为两个部份来进行，第ㄧ为外部轮廓线，萃取的方式是利用霍夫转换及其他附加几何条件来进行；第二为内部结构线，萃取的方式为利用相邻屋顶面的交会来获得；最后再将此二种特徵线合并在一起，进而重建完整的屋顶面形状。

By studying the datacloud processing technique for regular-shaped complex combined surfaces, an interactive approach is adopted to reconstruct parts' surface geometrical model from datacloud.

通过对规则形状的组合表面零件的数据云处理技术的充分研究，采用交互技术实现了由数据云到零件几何模型的重构。

In this dissertation, the numerical method and optical interferometry experiment for isothermal EHL of finite line contacts are studied. The effects of the profiles and the rolling velocity on the film shape, film thickness as well as pressure distribution of the film are discussed.

本文以滚子类轴承为研究对象，对等温有限长线接触弹性流体动力润滑理论的数值分析方法和光干涉试验进行了研究，探讨了等温油润滑条件下，光滑表面滚子的凸型、凸度量等几何参数和滚动速度与弹流油膜形状、油膜厚度和油膜压力分布之间的关系。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
