It can be used as Altazimuth mount when polar axis inclined to 90°.

它可以被用来作为经纬仪挂载时极轴倾斜90 °。

The physical model of polarizing beam coupling and splitting system using altazimuth coude telescope is built up based on Mueller matrix and Stokes vector. The phenomena of the decreasing of the receiving efficiency are successfully explained by this model. Three dynamic phase compensation solutions are proposed: 1 Two quarter-wave plates are rotated to compensate the phase of the laser.

针对这个问题，建立了地平式折轴望远镜的共孔径偏振耦合分光模型，用Stokes矢量和Mueller矩阵分析了在望远镜旋转过程中激光偏振态的变化，数值模拟计算了望远镜处于不同方位角和天顶角时的偏振耦合分光效率，解释了实验中观察到的望远镜旋转导致偏振耦合分光效率退化的现象。

When the optical fiber polishes, the motor leads the polishing disc to do revolving and swinging motion through vertical eccentric shaft by two synchronizations rotary motion with the ambulacrum.

光纤抛光时，电机经同步带带动两个同步旋转运动的立式偏心轴从而带动抛光盘作旋摆运动，光纤端面在外力的作用下紧压在抛光盘上，依靠光纤端面与贴在抛光盘上的固着磨料磨具之间的摩擦从而达到对光纤端面的抛光作用。

In practice, when coordinates of two angular of two beam of LD/PSD are measured, people can gained the relative position.

在实际测量中，只要测量双光束LD/PSD 在两个角度时光斑的坐标，即可求得两轴的相对位置。

The results showed that the angular velocity was relevant to performance parameter of granular material and filling ratio.

从圆周运动和轴向运动两个方面分析混合发生时颗粒物料运动的模式及加料方式对混合效果的影响。

When measured along axes in different directions,the velocity of light transmission is anisotropic.

当沿着不同的方向的轴测量时，光的传播速度是各向异性的。

Order in which they are expressed from anterior to posterior in the developing embryo .

这类基因常常成簇出现，在胚胎发育过程中，其活化顺序与生物纵轴的空间表达时相相符。

In order to deduce the engine control law during the helicopter autorotation, simulation was made to demonstrate the transient process of the engine when entering the helicopter autorotation condition using normal control law. Based on the existing control law, an improved law was brought forward by magnifying the differential gain of collective pitch "anticipator" and broadening the deceleration limitation.

为确定直升机自转下滑训练过程发动机的控制规律，分析了采用正常控制规律进入自转状态时涡轴发动机的变化过程，提出了在现有控制规律基础上增强动力涡轮转速控制模块中总矩"提前器"作用和适当放宽速率限制值的控制对策。

He also figured out the planet goes faster when it's at perihelion, nearer the sun, than when it's at aphelion, its furthest distance. Which would explain why summer seems to zip by, except the seasons are a function of the tilt of the earth's axis, not its different distances from the sun.

他还计算出地球在近日点时运行速度，比在远日点更快，这就可以解释为什么夏天好像比较短，另外，季节与地球轴的倾斜相关，不是因为地球与太阳距离远近的不同而造成的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
