The modeling and analysis method, as well as the conclusions are helpful to the design, fabrication and application of FMAV. Based on the real structure of the forewing and hindwing of dragonfly, the plane geometric models of biomimetic wings are created using some CAD software.

本文基于蜻蜓真实的翅翼样本，利用相应CAD软件分别建立了前、后翅翼的几何结构模型，并通过选择适当的单元类型及设定特性参数，完成三维仿蜻蜓前、后翅翼的有限元建模。

Element connect with each other by notes,and force are transfer through notes,the unknown of inner point of element can calculate by formulator .

因为脊柱的几何结构复杂，单纯的有限元软件在模拟椎体外形效果不是很理想，采用Unigraphics V17。

In the twentieth century, David Hilbert employed axiomatic reasoning in his attempt to update Euclid and provide modern foundations of geometry.

古典文书允许在几何结构的指南针和直尺。

Remarkable is that this more than a century ago almost directly with the achievement of modern mathematics, the following methods, the general flow is concepts, algebra to geometry closely linked, he and his successors -- Beiertelami, Christopher Tuofeier, Lee Puxici developed differential Zhang volume analysis has gradually become more research on the flow geometry and analysis of an important tool.

令人赞叹的是，这一个多世纪前的成就几乎直接同现代数学中的拓扑方法、一般流形概念、代数几何学等紧密相连，他和他的接班人——贝尔特拉米、克里斯托费尔、李普希茨所发展的微分张量分析逐渐成为研究流形上几何结构和分析的一个重要工具。

Using geodesic distance to discover the intrinsic geometry of the manifold,the geodesic Gabriel graph was constructed to locate the critical local regions where the local linear discriminants would be learned.

利用测地距离表征流形的内在几何结构，由此构造测地Gabriel图确定异类数据相互靠近的局部临界区域，进而训练得到局部线性的判别器。

This paper presents a layered polynomial texture to represent grass based on its complex geometric structure and diffuses material.

根据草的几何结构复杂性和材质的漫反射特性，提出层次多项式纹理(layered polynomial texture，简称LPT)来表示草，可以高效真实地实现这个目标。

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.
