On the basis of an analysis on the characteristics of image formation of roof Abbe prism and of the structure of double Dove prism, the paper presents a reflecting image rotator consisting of mirrors.

在对立方棱镜的结构特性和阿贝棱镜的成像特性分析的基础上，提出了由反射镜组成的反射式像旋转器，并证明了该反射式像旋转器在平行光路中的像旋特性。

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。

The effects of small angle rotation of texture images and noise to the parameterestimation of Gauss-MRF model are researched.

研究了工件表面纹理图像的小角度旋转和噪声对高斯马尔可夫随机场模型的参数估计的影响，数据分析表明高斯马尔可夫随机场模型所估计的参数对于小角度的旋转纹理具有不变性。

In this thesis, the concept and some key technologies of rotor wing plane are discussed, the primary theoretic analysis and experimental investigation in react driving rotor and stopped wing are studied.

本文对旋转机翼飞机的概念与涉及到的关键技术进行了探讨，进行了桨尖喷气旋翼技术和旋转机翼飞机机翼技术的初步理论和试验研究。

The traditional Givens rotation algorithm involves root computation which need more hardware resources, the paper presents a Givens rotation algorithm without root and division computation, combined with the special structure of the input signal matrix, a interference suppression algorithm with low computation is also proposed.

传统Givens旋转算法涉及到平方根运算，这种运算要消耗较多硬件资源或需要多次循环来实现，文中给出一种无平方根与除法运算的Givens旋转算法，并结合信号输入矩阵的特殊结构，给出一种低复杂度的干扰抑制算法。

This is because the jet particle velocity of the swirling water jet is three-dimensional, and its rock-breaking manner mainly has a slopping impact. Thus, the interference from returning fluid is less. All these aspects make it easy to draw and shear the rock surface.

计算结果与试验一致，表明旋转射流具有较强的破岩能力，其原因是旋转射流的质点具有三维速度，破岩时以倾斜冲击为主，易于在岩石表面形成拉伸和剪切破坏，回流的干扰较少。

In this film, shot in New York City in 1898, a boy performs a wild acrobatic routine. See if you don't recognize some of his moves. Pay special attention to the part where he stands on his head and twists around like a top. It looks pretty similar to the head spin move that is so popular in break dancing, doesn't it?

街头舞蹈已经兴起好几年了；这部拍摄于1898年纽约街头的电影中，有个男孩正在表现一个狂野特技动作，看看您是否认得他的一些动作，特别注意他用倒立后，用头旋转那一部分，它看起来与现在很流行的霹雳舞招式头部旋转是不是十分相似呢？

Earth records time by solar revolutions or how long it takes your solar system to rotate around her twelfth-dimensional sun.

地球以太阳旋转记录时间，就是你们的太阳系围绕着她的第十二维太阳旋转一圈所需要的时间。

Comparison between the stress of swirling and common jet nozzle tells that the former maximum stress is far larger that the latter. It can explain that the wear of swirling jet nozzle is more severe than common jet nozzle. The way how various parameters effect the wear of the nozzle is carefully studied in the article.

对比了旋转磨料射流喷嘴和普通磨料射流喷嘴的应力情况，结果表明：前者的最大应力远大于后者，这可以很好地解释旋转磨料射流喷嘴比普通射流喷嘴磨损严重的现象。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
