变换点

As the contour of a wheel rim is easier to detect than the contour of a wheel, and the contour of a wheel rim and the contour of a wheel are approximately concentric circles on the same plane, we first detect the contour of the wheel rim, the center of the wheel rim and the contacting point between the wheel and the ground, then we detect the contour of the wheel via the invariance of cross ratio under projective transformation.

由于提取钢圈轮廓比提取车轮橡胶轮廓容易，而且钢圈轮廓和车轮轮廓可以近似看作同一平面上的两个同心圆，所以在本文中，我们首先提取钢圈轮廓、钢圈圆心和车轮与地面接触点在图像上的投影，然后利用射影变换保持交比不变的性质求出车轮轮廓。

Temperature dependence of the the vibration frequency and the mean number of phonons for weak-coupling magnetopolaron in an asymmetric quantum dot were studied by using Huybrechts linear combination operator and Lee-Low-Pines variation method.

采用Huybrechts线性组合算符法和Lee-Low-Pines幺正变换法，研究了非对称抛物量子点内弱耦合磁极化子的振动频率和声子平均数的温度依赖性。

Existence Result for Semipositone Second-Order Three-Point Boundary Value Problem

利用不动点指数结合平移变换的方法，研究了一类四阶奇异半正边值问题，得到了其C~2[0，1]∩C~4(0，1)正解存在的一个新结果。

From combining internal force calculation with design detailing, some calculation simplifications and hypotheses are first presented, then a calculation method and corresponding formulas of internal forces for elliptical spiral stairs are derived.

采取计算与构造相结合的方法，进行必要的计算简化和假定，在椭圆形旋转楼梯的内力计算时，把固定坐标变换成动点坐标，推导相应的计算公式。

If the new font doesn't line up how you want to hit to free transform the new letter.

当你使用自由变换工具时，可以移动中心锚点，自由拉大或变小，确保这些字体基线都排成一条线。

A method of the soft registration based RST transformation is put forward on the basis of the hard registration in consideration of the speciality of 3 D image reconstruction for the serial sections of palatal microstructure. Employing characteristic points, the problem of displacement on 3 D image reconstruction for serial sections of palatal microstructure was solved and paved the way for reshowing the palatal microstructure with reality.

针对显微腭部序列切片图像三维重建的特殊性，在硬定位的基础上，提出了一种基于RST变换的软定位方法；利用特征点，解决了显微腭部组织序列切片图像在三维重建过程中的错位问题，为真实再现腭部组织结构打下了良好的基础。

Rotating transform, the formation of a 40 point, the diameter of 100 and 200 the diam...

用旋转变换的方法生成一个有40个点，内径为100，外径为200的星形图形。

So he didn't think this suited us. We also need more clothes cos it is cold in Cotopaxi and weather changes quickly as El Boliche.

他还特别提醒衣服要多穿点，温度很冷，且气候变换很快，就跟El Boliche一样，明明还是晴朗的天空，突然就变成大雨，这我们倒是很深刻的体认到了。

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。
