测地线

Concept of using geodesics cutting analysis of membrane structure is a complex issue, because the geometry of the novel membrane structure variable ...

用 测地线概念作膜结构裁剪分析的问题之所以复杂，是因为膜结构几何外形的新奇多变。。。。

Anosov generalized the work of Hadamard to geodesics on negatively curved manifolds with variable curvature.

Anosov 将 Hadamard 的关于常负曲率表面关于测地线的研究推广到变曲率。

The problem of sub-Riemannian geodesics is a Lagrange problem with constraint. How to describe the constraint condition "γ'∈ D, a. e." is a difficult problem.

次黎曼测地线问题是变分学中的一个有约束的Lagrange问题，但在变分的过程中有个难点―如何推出约束条件&γ'∈D，在上几乎处处成立&的解析式。

There is also an introduction to some concepts of General Relativity; principle of equivalence; the Schwarzchild metric; gravitational red shift, particle and light trajectories, geodesics, and Shapiro delay.

另外简单介绍广义相对论的一些概念；等效性原则； Schwarzchild史瓦西度规张量，重力红移，粒子与光的轨道，测地线，及 Shapiro 时间延迟。

Firstly, there are two types of winding patterns for toroidal vessel: spiral winding along toroidal vessel geodesics and analogous sine placement along the external surface of toroidal vessel.

首先，环形容器缠绕线型主要有两种类型：沿稳定测地线的螺旋缠绕和类似正弦外包罗铺放。

You have chosen geodesic dome .

你选择了测地线拱顶。

You have chosen arc edge dome , geodesic dome .

你选择了弧棱拱顶，测地线拱顶。

The geodesic dome was associated with the same sort of progressive thinking in design that led to the wind turbine.

导致测地线拱顶出现的渐进式设计思维，也适用於风力机。

Built geodesic dome , geodesic dome , dense grid, dome , geodesic dome , polyhedral dome .

测地线拱顶，短程线拱顶，密网格穹隆，网格球顶，多面体穹窿。

Edward Tenner, author of "Our Own Devices: How Technology Remakes Humanity," sees in the rise of the wind turbine parallels to icons like the compact fluorescent lamp, the geodesic dome, even the railroad.

不只是发明；科技改造人性》一书作者爱德华。田纳认为，风力机的兴起，足以和小型省电日光灯、测地线拱顶，甚至铁路等图腾等量齐观。

I bought a nice wrist watch as a surprise for my wife's birthday.

我买了一个漂亮的手表想要给我妻子的生日一个惊喜。

We don t expect students to be sponges. You can t expect to absorb everything and not have any questions to ask.

我们并不期待我们的学生是一块海绵，你没可能接收所有的东西而不提出任何问题。
