曲面元素

To solve the problem, the method that all the elements of the image of dual absolute quadric are transformed into the same magnitude is proposed.

提出了一种变换法，使对偶绝对二次曲面像的各个元素变到同一个数量级上，可以使求解过程更具有鲁棒性。

The available camera self-calibration is based on the image of the dual absolute quadric, but its elements have so large differences in magnitude that solutions are extremely sensitive to noise.

现有的自定标技术一般都是基于对偶绝对二次曲面像，由于对偶绝对二次曲面像元素在数量级上相差较大，在求解时必然会导致鲁棒性较差。

As basic element of CAGD, representation, design, display, analysis and handle of curve and surface is main task of CAGD.

作为CAGD系统基本几何元素，自由曲线、曲面的表示、设计、显示、分析以及规格、处理(包括数据结构、数据库、图形的信息形式和调整方式等)问题，是计算机辅助几何设计的主要研究对象和内容。

A ruled surface of revolution formed by an edged circle as the guide element is proposed in the category of basic geometrical bodies.

摘要在基本几何体的范畴内，提出一种以棱圆为导元素的直纹曲面。

The shell, and the winding pathway into and through the sacred space - another version of Le Corbusier's "promenade architecturale"- are the central elements of Saint-Pierre.

这一由直纹曲面围和的斜截锥体以及蜿蜒而上、导入并穿越圣殿的坡道——柯布新版的"散步建筑"——构成了圣皮埃尔的中心元素。

Based on the garment design with the meshes, we assort spline curve into two types, that is to raisene idea that the ring and characteristic line are the basic geometry elements of three-dimensional garment model.

从人体服装设计所用曲面出发，通过对样条曲线进行分类，提出将环和特征线作为人体服装三维建模最基本的几何元素，并详细介绍了利用双线性插值法对人体服装中的两类子曲面进行三维建模的方法，从而在将参数化方法运用到高层次图素如样条曲线、曲面等方面作了尝试和推广

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
