In order to improve the energy efficiency and image contrast of liquid crystal display projector, a wide-angle and broadband optical thin-film polarizing beam splitter was designed.

为提高液晶投影机的光能利用率和图像对比度，设计了一种宽角度宽波长的光学薄膜偏振分束器。

Chapter three .introduce the design principal of crystal polarizing prisms and beam splitter prisms, introduce phase retardation plate in short.

第三章介绍了晶体偏光棱镜的及偏光分束棱镜的设计原理，简要介绍了相位延迟器件和退偏器件。

Based on the Jones matrix, using polariser, beam splitter and lock-in amplifier and microprocessor, a testing and automatic processing system for the data was constructed.

从琼斯矩阵理论出发，利用偏振镜、分束器和锁相放大器以及微处理器，搭建了测试系统，实现了数据的自动化处理。

St. Clare will have high life below stairs and they every one of them live just as they please

可是圣·克莱亚偏要让下人享福，于是他们一个个就都为所欲为了。

It's abominable, to be sure, but St. Clare will have high life belowstairs, and they every one of them live just as they please.

这种现象实在令人难以忍受，可是圣·克莱亚偏要让下人享福，于是他们一个个都为所欲为了。

The results show that overpressure bench mark is well suited for describing anomaly distribution, and momentum bench mark can provide better measure for shockwave damage. Along with increasing of the branch deflexion angle, the primary tunnel momentum increases and the branch tunnel momentum decreases, and plane shockwave recover distance also increase but will not exceed six times equivalent diameter.

研究结果表明：超压准则适用于描述分布的不均性，而冲量准则能更好地衡量分叉巷道中冲击波的破坏作用；分叉角度的影响较大，随着分叉偏转角的增大，主巷道内冲量将增大而分巷道内冲量将减小，恢复"平面波"的距离也增大，但不超过6倍巷道等效直径。

If you know the ball is low the tendency would be to bend down to reach it.

一旦你发现这个球很低了，自然会有屈膝的动作去保持一种偏低的倾向回击来球。

So it is necessary to study on how to calculate bending moment utilizing the result of FEM.

这类结构在有限元计算中也易出现位移计算值偏小的剪切闭锁现象。

He's an affable character, slightly overweight, smiling benevolently at the world from behind a gray beard and oval wire-framed glasses.

他是一个和蔼可亲的人，略微偏胖，从灰色胡须和卵形金属边眼镜后面向世界投以仁慈的微笑。

Although hasten of near future of upriver cooking benzene is firm, but the range that the market rises is not big, each manufacturer is maintained more move smoothly, the amplitude modulation on shipment price is lesser, to suitable anhydride market prop up gradually firm, if crude benzole market goes high further, driving the possibility that cooking benzene rises is not to do not have, the crude benzole stock of manufacturer of each cooking benzene and benzene hydrogenation manufacturer is not at present much, the crop of cooking benzene is not big, market supply of goods is not much, do not eliminate small to walk along high probability.

虽然上游焦化苯近期趋稳，但市场上涨的幅度不大，各厂家多维持平稳运行，出货价格上调幅度较小，对偏苯三酸酐市场的支撑渐稳，若粗苯市场进一步走高，推动焦化苯上涨的可能性不是没有，目前各焦化苯厂家和苯加氢厂家的粗苯库存并不多，焦化苯的产量不大，市场货源不多，不排除小幅走高的可能。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
