圆的

Computer graphics simple linear and circular painting of a simple realization of the two paintings linear method, a method Circle.

计算机图形学的简单的画直线和圆的简单实现，两种画直线的方法，一种画圆的方法。

From Poisson matrix, we can observe volume-preserving vector fields. By using Geiges-Gonzalo's existence of contact circle Theorem [3] , we show the existence of volume-preserving circle on3-manifolds which says that every3-manifold admits two linear independent vector fields preserving a same volume form.

通过Poisson矩阵可以观察出保积向量场，再利用Geiges-Gonzalo的接触圆存在性定理[3]，我们证明了保积圆的存在性：每个闭的3-流形上都存在两个处处线性无关的保积向量场并且它们的常系数线性组合仍是保积向量场。

Sweeping the hand in an arc, walking in a circle, positioning the fingers like an orchid, for example, are all endocentric and implicit.

中国戏曲里面所有的动作都是圆和的，比如说拉云手、跑圆场、兰花指，所有的动作都是圆的，向内的，都是含蓄内敛的。

Since representation of the subclass object starts out like the representation of a superclass object, the circle can always pretend to be a point — at the initial address of the circle's representation there really is a point's representation.

因为子类的表示开始于一个非常像其父类的结构，所以圆可以把自己伪装成一个点——圆的物理表示的地址的前面部分就是一个点的表示。

Then the system parameters were gain from solving non-linear equation. First, the figure which the circle projecting on the CCD plane by the camera led is proved as an ellipse, and find out the reference point coordinate by calculate the canters of ellipses. Then the system parameters were gained from calculating the formulas in two pictures.

首先证明了参考圆在合适条件下经过相机镜头所成的像是椭圆，通过椭圆的中心求出参考圆的中心，就得到了各个参考点的位置；然后通过各个参考点分别在两个相机坐标系中的位置来确定相机之间位置关系参数，就完成了系统的标定。

The ellipse curre equation of circular image is derived based on the theory of spatial analytic geometry and rotation matrix s representation with unit quaternion then a mathematical model of the distortion error is established which relates the distortion error to the foca length of the used CCD camera,the radius as well as the position and the attitude of the inspected circle directly.

研究三维视觉检测中圆的中心经针孔摄像机成像后存在畸变误差的问题，首先基于空间解析几何理论和旋转矩阵的四元数表示法推导出像平面上投影椭圆的参数方程；然后根据参数方程建立圆中心成像畸变误差的数学模型；最后对影响畸变误差的主要因素进行分析。

By rotating the X-axis of the measurement coordinates, the straightness data of each generatrix are transformed into a unified 3D coordinate system whose Z-axis superposes the least square mean axis calculated with the data of the multiple generatrices. The computer simulations and experiments prove that the construction by rotating the abscissas can effectively eliminate the distortion of the constructed profile.

通过测量坐标系中X轴的旋转，将各条母线直线度偏差数据统一到同一个空间坐标系中，采用两端面圆的最小二乘轴心的连线作为零件轴线，消除了直接构造所带来的表面变形，并能进一步计算出被测内孔的直径、圆度和轴线直线度误差，使测量系统集成化和多功能化。

With the unemployment high , the dollar low, and the stock market in distress, the economy became the President's sternest trial.

随着失业人数的增长，美圆的贬值美圆的贬值，股票市场的不景气经济问题成了总统最严峻的考验。

The Pembroke features rounder ears and is somewhat smaller in stature. The tails of Pembrokes are traditionally docked to a flat-lying stub, making them appear tailless.

卡提根是两种中较大的有著较大的圆耳跟狐狸般下垂的尾巴，潘布鲁克的特徵则是较圆的耳朵跟较小的身材。

In one of our Battle Report considered replays, I have actually seen 2-3 Nullifiers brought straight into the enemy resource line, then all exits force fielded so the enemy drones couldn't get out, and the Nullifiers pretty much killed a large amount of them easily since they get bonus biological damage..

正在人们的一场曾经计划做成战报的来搁中，人确真顾到过2-3个可绝者直接冲入对于圆的矿场中，然先部合启力场，这样对于圆的农民（drones：农蜂，小约是虫族）即入没有去了。接亡可绝者宰了小质的农民，由于他们的守击对于死物体有减成。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
