三维空间

The graph of an image function is a surface in the three-dimensional space that appears like a landscape.

图像函数图在三维空间中所形成的曲面形状看起来像地形地貌。

"In the 16th century grisaille enamel s were developed in Limoges, France; the technique achieves a dramatic effect of light and shade and a pronounced sense of three-dimensionality."

16世纪时，纯灰色画珐琅艺术发展于法国利摩日，此技巧在光和影上达到戏剧性的效果和明显的三维空间立体感

A tetrahedral mesh with up to somehundred thousands nodes can be generated within hours with a personal computer.. By using the general harmonic mean of heat conduction coefficient, a new discretization method in the unstructured grid with anisotropic and heterogeneous media is developed.

生成的网格可以按照给定的纵横比实现剖分（纵横比可高达2000），这样就克服了非结构网格难于在粘性支层内使用的缺点；给出了切平面测度和主曲率测度矩阵的建立方法，结合各向异性网格生成技术，实现了三维空间曲面剖分，为三维实体剖分做了准备。

That the scales in the universe, at any time, three-dimensional space is homogeneous and isotropic.

认为在宇宙尺度上，任何时刻，三维空间是均匀的和各向同性的。

Complete cosmological principle is to further promote the cosmological principle that not only the three-dimensional space is homogeneous and isotropic, and the entire universe at different times are identical.

完全宇宙学原理是宇宙学原理的进一步推广，即不仅三维空间是均匀的和各向同性的，整个宇宙在不同时刻也是完全相同的。

In this thesis, we implement a real-time pointing system which, unlike ordinary 3D reconstruction approaches, uses homography and some known 3D reference planes to reconstruct the target point without using camera's intrinsic parameters and orientation. The basic concept is quite intuitive and easy to realize.

本论文中实作了一个即时的指向系统，不同於其他相关的研究中使用传统三维重建的方法来找出指向点，我们没有使用到相机的内部参数以及朝向等资讯，而是利用平面投影转换以及一些三维空间内的平面关系作为系统实作的基础，概念上较为直觉而且也相对地容易理解。

How many equal three-dimensional spaces would a hypersphere be cut into by hyperplanes at right angles to each other?

一个超球面被切割成相互垂直的超平面会产生多少三维空间？

If the mansion stood on a hypersphere slightly greater in diameter than the mansion grounds, a person could move from any point to any other with what, in three-space, would seem to be right angles.

如果这座大厦建造在一个比地基更多维的超球面上，一个人就可以从任意在三维空间内看上去是直角的地方从一点移动到另一点。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
