We propose a unified method to approximate important geometric attributes, including normal vector, gauss curvature, mean curvature, principal curvatures and principal directions on point sampled surface. Based on MLS projection our method is robust to noise and stable to the sampling density.

曲面的微分性质包括法向量和切平面、高斯曲率、平均曲率、主曲率和主方向，在计算机图形学、机器视觉和计算机辅助设计等领域发挥了重要的作用，比如曲面绘制、内外测试、曲面重建、曲面简化、去除曲面噪声和模型分割等。

G = Ω×(0,+∞),F =Ω× 0,+∞, A is the Laplace operator, n is the unit exterior normal vector toΩ.

是边界Ω的单位外法向量。

For each potential instability mode,a critical point on the boundary of the security region was found,in which the normal vector was used to form the hyperplane to simulate the boundary of the s.

对每一种潜在的失稳模式，搜索其动态安全域边界上的一个点，根据临界点处的法向来求解用于模拟动态安全域边界的超平面。

OpenGL takes into consideration the length of the normal vector when computing lighting.

OpenGL在计算光照的时候需要考虑归一化的法向量。

Nor: Uses the direction of the normal vector as coordinates.

法向：使用法向量的方向作为坐标。

Also how to calculate normal vector of the original surface is introduced.

在第三章，介绍了特征的准确定义，并介绍了特征提取算法，并在特征提取的算法中，介绍了一种计算网格曲面顶点法向量的比较好的方法。

Where 、and is the direction cosines of the normal vector of the directed surface at the point .

其中、、是有向曲面在点处的法向量的方向余弦。

We do the same for the normal vector

我们为法向量顶点做同样的事情。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
