During building 2D model, I use the concepts of point, segment, line and plane, the segment can be formed from points, then line can be formed from segments, the closed curved plane can be obtained by around lines, and finally the 2D model can be built by closed curved plane; I express the un-smooth stratum or fault by linear fitting and express the smooth stratum or default by cubic spline fitting segmentally, in this way I can describe the variation feature of 2D interface properly.

在二维建模中，引用点、段、线、面的概念，即由点形成段，由段形成线，由线围成封闭面，封闭面构建成二维模型；对表示二维地层和断层的界面线，用线性拟合表示非光滑性地层或断层面，用分段三次样条拟合表示光滑性地层或断层面，恰当地表达了二维界面的变化特点。

Moreover, since the strain energy of zigzag tubes is larger than that of the armchair tubes with the same semidiameter, the ends of the armchair tubes are easier to be closed than those of the zigzag ones. And the closed structures of the zigzag tubes have a lot of defects, even at 3000 K, there will be few carbon atoms flying away from them.

此外，由于锯齿型碳管应力能比同口径扶手型碳管的应力能大，使得扶手型碳管比锯齿型碳管更容易形成端口封闭的结构，且锯齿型碳管端口的封闭结构出现相对较多的缺陷，甚至在3000K下会有少最碳原子从端口飞离碳管。

This kind of house absolutely abandons the European and American styles in the architectural design but employs more Chinese traditional residential elements, such as the pitched roof, wall, blue tile and white wall. What's more, especially in the large spatial layout, this building advocates the closed and semi-enclosed spatial arrangement in response to the psychological characteristics of Chinese people, restraint without showiness. However, the interior life circulations without exception absorb the European lifestyle to show the life philosophy and value orientation.

这类住宅的主要特点是在建筑设计上摒弃了完全欧美化的做法，而采纳了较多中国传统住宅的元素，如坡屋顶、院墙、青瓦白墙，特别是在大的空间结构上，提倡封闭、半封闭的空间围合方式，以契合中国人内敛含蓄的心理特征，但在内部生活流线上几乎无一例外地吸收了欧式的生活方式，体现了现代都市人的生活理念和价值取向，项目配套都比较现代化，有公建、会所、游泳池等现代人所不可缺少的休闲和娱乐设施。
