物质使一束穿过它的光线的偏振平面发生旋转的能力，一如在晶体或溶液中。

Clamp and turn the telescope around the polar axis to set the observing date on the date graduation ring to the observing time on the R.A.

松开赤经制动钮并使望远镜围绕极轴旋转用以设置日期刻度盘上的观测日期对准赤经兼小时刻度盘上的观测时点。

The method comprises the following: a step of calibrating a camera, which is to utilize a Taylor series model to calibrate an omni-directional vision sensor so as to obtain internal parameters of the camera; a step of obtaining epipolar geometric relation, which comprises the steps of calculating an essential matrix between binocular omni-directional cameras and extracting the rotation and translation component of the cameras; a step of correcting an outer polar line, which is to correct the outer polar line of a shot omni-directional stereo image so as to allow a corrected polar quadratic curve to coincide with an image scan line; and a step of three-dimensional reconstruction, which is to carry out feature point matching to the corrected stereo image and calculate the three-dimensional coordinates of points according to matching results.

该方法的步骤包括：相机标定：利用泰勒级数模型对全向视觉传感器进行标定，得到相机内参；对极几何关系求取：包括计算双目全向相机之间的本质矩阵，并从中提取相机的旋转和平移分量；外极线校正：对所拍摄的全向立体图像对进行外极线校正，使校正后的极二次曲线与图像扫描线重合；三维重建：对校正后的立体图像对进行特征点匹配，根据匹配结果计算点的三维坐标。

The rotating chute planetary gearing of eoordination type double pot bell less furnace top of 750m 3 blast furnace in Laiwu Iron and Steel General Works can make chute to do circular motion around contral line or blast furnace of to do inclined motion, and it can achieve ideal charging of throat.

9 How do I rotate/cycle/randomize the image in the header of the weblog?

6.10我怎样在博客标题上使图像旋转/轮转/随机出现？

If using digital locator precision by increasing the control valves to improve valve control performance, successful applications have if ND800 digital positioner for rotary control valves, we can make a variable range of process parameters increased by 50%, and then with the the characteristics of control valve valve positioner of the electronic properties of the match to further improve the control performance.

如采用数字定位器通过提高控制阀的精度来提高阀门的控制性能，成功的应用有如果将ND800数字定位器用于旋转控制阀，就能够使工艺参数的可变范围提高50％，再通过与控制阀的特性阀门定位器的电子特性的匹配来进一步提高控制的性能。

Consequently, the spring arm 53 pivots the magnet from a position closely adjacent the play/record head 13 at a rate controlled by the unwinding of tape to a position farther therefrom as illustrated in FIG.

就算没停，取出来之前一定是停的，因此，相当于把一个磁铁放在距离磁头1CM左右的地方。淘宝的那些买家是基于这些原因给予好评的吗，dtape同学？？？？更具体的描述如何远离磁头：通过偏心旋转使磁铁逐渐远离磁头。

Convention V-belt Continuously Variable Transmission, shifts gears the travel mechanism property fixed constraint, unable full into full play initiative control advantage, to engine and Transmission on the go to hold optimum match, Also takes into consideration acceleration and fuel consumption performance, so this paper research Motorcycles with an Electronically-Controlled Continuously Variable Transmission shift gears planning, to use motor power screw, we shall revolve motion changes rectilinear motion, to push driving sheaves achieved to change speed ratio; Comparison between analysis convention CVT speed ratio shift gears curves of acceleration and fuel consumption performance optimum curves, use engine can hold high performance output or low fuel consumption region run.

中文摘要传统皮带式无段变速器(Continuously Variable Transmission， CVT)，换档行程由於机械特性的限制，无法完全发挥主动控制的优点，让引擎与变速器随时保持在最佳的匹配状态，同时顾及加速性能与燃油消耗，所以本文主要研究机车用电子控制式无段变速系统(Electronically Controlled Continuously Variable Transmission， ECVT)最佳换档规划，利用马达与动力螺杆，将旋转运动改变为直线运动，以推动主动滑轮达到改变减速比；分析传统CVT减速比换档曲线与最佳化曲线之加速性能及燃油消耗比较，使引擎能够保持较高性能输出或较低油耗区间运转。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
