折射

Calming down from grief, numerous artists take action by swift and general devotion of their beloved works for the charity auction, which represents the responsibility of a common citizen. Besides, such spontaneous almsdeed also reflects artists' sober conscience and selflessness in today's extremely prosperous art market.

哀痛之余，众多的艺术家行动起来，为赈灾义拍迅速而慷慨地捐献出自己心爱的作品，这不仅体现出作为普通公民的责任，在艺术市场极度繁荣的今天，这种自发的善举更折射出艺术家们清醒的良知和无私的激情。

In this thesis we investigate the beam propagation and amphoteric refraction in a Uniaxially anisotropic crystal.

本文在理论上研究了单轴晶体中的光束传输和正负折射现象。

Angle of Incidence The angle between an incident ray and the normal to a reflecting or refracting surface.

入射角度入射光与照射在反射或折射平面上的正常光线之间的角度。

The angle of refraction, r, is the angle between the refracted ray and the surface normal.

折射角 r 是折射光线和表面法线间的夹角。

Refraction regularity of extraordinary ray in uniaxial crystal with arbitrarily oriented optical axis;2. In the case of optical axis of uniaxial crystal being parallel with the incident plane, the angle of refraction of extraordinary ray are calculated by using Fermat's principle.

在单轴晶体的光轴与入射面平行的情形下用费马原理计算非寻常光光线的折射角，然后就怎样定义非寻常光作些讨论，最后在单轴晶体的光轴任意取向的普遍情形下给出计算非寻常光光线折射方向的公式。

The next in order, the thesis takes the undergraduate managerial mode in the United States as the representative of North America university and with Hong Kong for refracting Anglicism university, then respectively generalizes and analyzes the mode and formative reason.

其次，就以美国为代表的北美高等教育学生管理工作模式和以香港为折射的英国式高等教育的学生管理模式及其成因进行了概括分析。

The calculations show that the approximation for the birefringence and the rotatory property of interaction material leads to an error in the optimum incident angle for TeO2 more than 10%, a diviation in fa-λ0 relation from experiment results, and make the spectral resolution and angular aperture of the device to be degrade.

结果指出，在该波长下，对晶体双折射取近似表达式和不计入晶体的旋光特性，对光波最佳入射角θi的选取(在θi小于60°的范围内)，将引入大于10%的误差，这个误差由于涉及到是否满足动量匹配条件，因此会对器件的性能有直接的影响。

Correlation between spin angular momentum s and background angular momentums of planets;2. In the paper the principle of optical rotation due to the transfer of spin angular momentum from light to particles was discussed by analyzing the interaction between the beam of light and birefringent crystal particles, and then an optical tweezers was formed on nanometer optical tweezers system with a linearly polarized light beam (He-Ne laser 633 nm, 10 mW).

从理论上分析了偏振光束与双折射晶体粒子的相互作用过程，讨论了由于光束自旋角动量向晶体粒子的传递所导致的光致旋转效应的原理，并在纳米光镊装置上利用线偏振He Ne激光器(633 nm，10 mW)形成了光镊光阱，利用1/4波片来改变光镊光束的偏振状态，在不同的椭圆偏振状态下实现了直径约为几微米的CaCO3 晶体微粒的捕获和光致转动。

When there is an angle between the anisotropic metamaterials' optical axis and the electromagneticwave propagation axis, anomalous omnidirectional total reflection and anomalous negative refraction are discovered at the interface.

当电磁波的传输轴和各向异性超常介质的光轴成任意夹角时，发现在界面处可以产生反常全向全反射和反常负折射现象。

The air through which we view Antares causes this star to twinkle rapidly!

空气的折射使得心宿二在我们眼中一直闪烁不断。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
