In strictly, it is hard to make the light normal incident into the sphere, double refraction will take place in crystal sphere when a TEM〓 mode Gaussian beam oblique incident into the sphere, and the two orthogonal polarized beams are both elliptical Gaussian beam. The ellipticity and eccentricity of the elliptical Gaussian beam will change with the incident angle, and for a fixed incident angle, they will change with the shifting of incident beam waist position.

由于严格意义上的正入射较难实现，基模圆高斯光束斜入射晶体球后将在球内产生双折射，且球内偏振态正交的两束折射光都将是椭圆高斯光束，它们的椭圆度e和偏心度Δ随入射角的改变而改变，在入射角一定的情况下，入射光束束腰的移动也将改变这两束折射光的椭圆度e和偏心度Δ。

This paper researches a optical sensor and a new method for product oil identification and mixed oil distinguish and calculates the light intensity of the Fresnel reflection occurred at the interface between the product oil and a measuring probe. The product oil and oil mixtures are analyzed by using the principle of energy conservation and the inductor model of an electron cloud.

When the temperature changes, several device parameters such as the transmittance, the extinction ratio and the curve of the transmittedintensity will change accordingly for devices made of the Iceland crystal.

其次系统分折了温度对格兰·泰勒棱镜和格兰·付科棱镜的透射光强曲线的影响，利用光的干涉原理和不同振动形式的反射比公式，得到了格兰棱镜在同一入射波长、温度改变时的扰动因子极大值点的移动量以及相同的温度改变、不同人射波长时扰动困子极大值点的移动量。

This was also capable of reflecting economic and political aspects of the society at that time. President Lin Chun-shin pointed out that judged from Western art history, the painting before the eighteenth century would clearly delineate an object but there was a lack of the element of light. In the nineteenth century, Impressionist would raise the brightness of a painting through pointillism using three primary colors and come up with a feeling of light. Despite of the fact Vincent van Gogh's works had been systematically manipulated by painting dealers on the art market, the real reason for his paintings to excel after 100 years were his capability to apply pointillism techniques with distortion to express feelings, which could not be done by other painters.

林俊兴董事长表示，以艺术史的角度来看，十八世纪以前的绘画是将物体清楚描绘出来，但却缺乏光的元素，而十九世纪的印象派画家，却能运用三原色的点描提高画作中的明度，画出光的感觉；虽然梵谷的作品被画商有系统地於艺术市场推波助澜，但真正使其作品百年后脱颖而出的理由，是梵谷能把点描技法加上扭曲，表现出其他画家无法绘出的情绪。

When Qing Qing saw a ray of light again after 20 hours in the wreckage of her school, she cried desperately for water. She was fed small mouthfuls of mineral water, with the lid of the bottle, in case excessive intake might worsen her internal injuries.

当清清看到一个光的光后，再次在20个小时的残骸她的学校，她哭了拼命的水，她喂小mouthfuls矿泉水，与盖瓶，在案件过多的摄入量可能会恶化，她的内部受伤。

A pulsar is a celestial object that emits light in short burst a pulsar in the crab nebula flashes at a rate of 30 times/s,suppose the light pulses are caused by the rotation of a spherical object that emits light from a pair of diametrically opposed "flashlights" on its equator.

脉冲星是一种以短爆发形式辐射光的天体。假设球型天体赤道面上有一对&发光塔&，并且这对发光塔的联线构成赤道面的直径，进一步假设光脉冲产生于球形天体的转动，那么巨蟹座星云中的一个脉冲星的闪光频率是每秒30次。

If the thickness of the colored glass and the band width of the narrow-band filter now on hand is encreased properly, fine signal-to-noise ratio and resolving capability of fluorescence imaging can be obtained.

根据有色玻璃的吸收特性，实验时适当增加光在玻璃中的行程和带宽，使信号和背景光的透过率之比增大，从而得到较好的荧光像的信噪比和分辨本领，提高了图像目视探测的灵敏度。

According to the current high real time peculiarity and high precision demands of beacon beam processing subsystem of space optical communication and the requirements of our project, the method that uses digital signal processor to solve the image position error signal extraction of beacon beam is proposed in this dissertation. It have the following advantages: the small system volume, the slight weight, the small power, the high real time peculiarity and the high precision and so on.

根据目前空间光通信对信标光处理子系统提出的高实时性和高精度性的要求以及课题的需要，本论文提出用数字信号处理芯片DSP来解决空间光通信中信标光的像面位置误差信号提取的问题，其优点就是系统体积小、重量轻、功耗低、实时性高、精度高等。

Our sky chart shows Orion for about one hour after nightfall. The three stars of Orion's belt jut pretty much straight up from the horizon, with the bright ruddy star Betelgeuse shining to the left of Orion's belt and the bright blue-white star Rigel to the right of the Belt.

星象图指出了夜幕降临一个小时后猎户座的状态，猎户座腰带上的三颗星星正好和地平线平行，闪着红光的 Betelgeuse 再要带的左边，闪着蓝白光的星星 Rigel 在要带的右边。

About the light, I would talk about the colour spectrum, and I remember looking at a Monet painting The Cliffs of Deauville, and he had obviously painted the light up from the rain at the cliffs of Deauville, so what you looked at was rain in an impressionistic way falling over the cliffs, which took you right through the colour spectrum.

关于光，我想谈论一些关于光谱的问题，我记得看过莫奈《杜维尔的悬崖》这幅画，很明显他把悬崖上雨水反射的光线描绘了出来，所以你看到的是雨水以一种印象派的方式流下悬崖，这种方式令观者感受到光的变幻。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
