棱镜的

Then according to the cascade of IPS and LPS, the multi-stage rearrangeable nonblocking Omega network was introduced. Moreover, the method of bipartition graph was adopted to ascertain the node state of each stage. At last, a module of the rearrangeable nonblocking Omega network, which was integrated with polarizing beam-splitter,λ/2 wave plate and perfect shuffle Plates, was constructed.

该方法通过逆混洗(Inverse Perfect Shuffle， IPS)和左混洗(Lott Perfect Shuffle， LPS)的串联，构成多级的可重排、无阻塞的Omega网络，采用二分图法依次确定各级节点开关的状态，最后通过偏振分光棱镜(Polarizing Beam Splitter， PBS)、半波片(λ/2 wave plate)和PS Plate的组合，得到可重排、无阻塞的Omega网络交换模块。

Measuring light wavelength with biprism interference is a very important experiment in the research and teaching of basic physics, the key to which is the distance measurement of the two virtual images.

用双棱镜干涉测量光波波长是基础物理研究和教学中非常重要的一个实验，该实验的关键环节是测量两虚相干光源间的距离，大多数实验教科书中大都采用二次成像法测量两虚相干光源的间距。

Because the change of grating period caused by the asymmetrical rotation of two beams is limited to 5×10-4 nm at a tunability of the Bragg wavelength of ~100 nm, the tilt of grating caused by the rotation of the biprism can be ignorable.

因为在~100 nm范围内两光束的非对称旋转对光栅周期的改变是5×10-4 nm，双棱镜引入的光栅的闪耀可忽略。

The request for exit pupils as large as 7.1mm leads to either small fields of view or, if an apparent field of 60 degs. or more is wanted, to a sophisticated design with either huge prisms or semi-apochromatic objectives.

大到7.1mm的出瞳直径的需求，导致要么是小视野；要么是：如果表现视场想达到60度或更大，老练的设计是需要巨大的棱镜或半消色差物镜。

The positions at cavity mirror of ray which propagates back and forth in the CCP laser resonator are analyzed, it shows that the CCP resonator with three equal dihedral angle errors (three dihedral angle errors are not 0) is an unstable resonator.

对在腔内往返传输的光线在镜面上的位置进行了分析，结果表明：3个二面角误差相同且不为零的角锥棱镜构成的谐振腔为约束非稳腔。

The working mechanism of Wollaston prism differential interference contrast method is introduced, and by this method, the processes of ignition, backfire, flameout are observed. The effects of the stabilizing rod on v-flames are also researched.

介绍了Wollaston棱镜差分干涉仪的工作原理，用差分干涉法研究了预混V形火焰的的点火、熄火和回火过程的特性以及稳定杆对V形火焰的影响。

Because of its dispersion, technical parameters of polarizer are influenced by wavelength.

但由于晶体材料本身的色散，导致由它制做的棱镜型偏光器件的技术参量受入射光波长的影响。

With the sustaining development of modern optics, especially the emergence of laser, polarizers are becoming more and more widely used.

随着现代光学的不断发展，尤其是激光出现以后，偏光器件的应用越来越广泛，特别值得注意的是适应激光应用特点的激光偏光棱镜应运而生。

If you take sunlight and spread it out into a spectrum you'll reveal all the colours of the rainbow — Isaac Newton first managed this with a glass prism, but nowadays we use very precise diffraction gratings.

如果你把它的阳光和蔓延到频谱您会发现所有的颜色的彩虹-艾萨克牛顿第一管理这一带有玻璃棱镜，但现在我们使用非常精确的衍射光栅。

In the course of testing, the laser was used as light source with twin-light path, dispelled the error of light-intensity variation of traditional detection devices, the measurement result only relates to the relative change of optical intensity .

测量以激光为光源，采用双光路法，消除了通用检测仪由于光源光强不稳定产生的误差，使得测量结果只与光强的相对变化量有关；光波出入波导均采用棱镜耦合，减少了普通测试方法因样品质量及面形误差和端面洁净情况不同或输出透镜不能很好汇聚光波而产生的误差；利用常规仪器设备实现了数字化检测显示，避免了人为主观读数产生的误差；利用AD538实时模拟计算芯片，提高了计算精度和运算速度。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
