曲率

A couple of years later, Friedmann published his findings in About the Possibility of a World with Constant Negative Curvature of Space.

&几年后，弗里德曼发表他的研究结果&，对可能出现的世界恒定负曲率空间。

The Curvature Scale Space is employed to detect the feature points.

提出了一种基于曲率尺度空间的图像拼接算法。

The corner is an important feature in image processing, an adaptive corner detector is proposed based on curvature scale space technique in this paper.

角点是图像处理中的重要特征，基于曲率尺度空间技术，提出一种自适应角点检测方法。

This paper presents a multi-scale curvature product corner detection technique in the framework of B-spline curvature scale space.

摘要本文在B样条尺度框架下提出了一种多尺度曲率乘积角点检测算法。

They all require an enormous number of scales to construct the curvature scale space image.

根据这些方法，构建曲率尺度空间所需尺度太大。

In this paper, a new method is presented to overcome this problem. By matching the 3D points reconstructed from the images and the known geometric model in space, the topology and curvature information of the model surface can be fully utilized and all the images to the 3D model stitched at the same time.

提出了一种新的配准方法来解决这一问题，由于采用了基于图像重建的采样点模型与已知几何模型在空间中匹配的方法实现配准，因而充分利用了物体几何形状本身的拓扑和曲率等信息，并可以一次性地实现所有图像与空间物体的配准。

He conceived of a space time continuum that is curved by mass; in other words, planets, stars, galaxies and other stellar objects cause a curvature of space time.

他的构想是一个时空连续弯的质量；换句话说，行星、恒星、恒星和星系等物体造成时空曲率。

The quality of an object the greater the density of the distribution of the greater, then the stronger the gravitational field, the greater the curvature of space; corresponding to the time flow more slowly.

物体的质量越大，分布的密度越大，则引力场愈强，空间曲率愈大；相应地，时间流程愈慢。

Using the method of Green's function, the coupling between conformal antennas is analyzed. The mutual coupling between the E plane and the H plane are calculated, and the effect of the curvature and space between to the mutual coupling are discussed.

本文利用格林函数法分析了微带天线阵元之间的互耦效应，得到了矩形微带单元阵元之间E面、H面的互耦结果，并讨论了圆柱曲率半径和阵元的间距对阵元之间互耦的影响。

It works by focusing a quantum field through a deflector dish to generate massive changes in local space curvature; this creates a subspace tunnel, which is projected in front of the vessel.

它的工作原理是是通过偏导仪盘聚焦量子场来急剧改变局部空间曲率；从而产生一道在飞船前端投射出的子空间通道。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
