被反射

In particular, some of the light is reabsorbed as it bounces around, and is lost as heat.

实际上，部分光线中在向四周反射时被重吸收了，这样光线就会象热量一样散失掉。

Light from a large core multi-mode fiber is launched onto the curved surface of plano-side-silvered plano-convex lens.The reflected light is recovered by small core multi-mode fibers and serves as the means for determining the displacenient of tilt.

从一个大直径多模光纤中发射出的光，入射到一个由平凸透镜和平面镜组成的系统的曲面上，光经反射后，被小直径的多模光纤收集，经处理后确定物体的位移和转动。

It is then reflected twice by the pentaprism, rectifying it for the photographer's eye.

然后为调整到摄影师眼中，光线被五棱镜反射两次。

This invention relates to a method and device for generating cold atomic beam. Said method includes heating hot atom source in vacuum chamber to form atomic saturated vapor pressure atmosphere, cooling hot atom by three-D MOT to below 200uk and trapped to form cold atomic cloud, by the quarter wave plate reflection mirror in MOT the laser radiation pressure being unbalanced to make cold atom emitting along said direction, four tape arranged straight line set with contrary current direction is set in atom beam emission direction, which makes the atom emitted to forward to obtain cold atom beam with low speed, large flux and small transverse speed, laser beam vertical with atom beam set in the direction of cold atom emitting for atom beam state preparation to realize state concordant emitted cold atom beam.

本发明涉及一种冷原子束产生方法和装置，该方法包括在抽真空的真空室内，加热热原子源，在真空室中形成相应的原子饱和蒸汽压气氛；采用三维MOT对热原子进行冷却，冷却到200μk以下，并被捕获形成冷原子云团；通过三维MOT中开小孔的四分之一波片反射镜，而使得在该方向上激光辐射压力不平衡，使冷原子沿此方向出射；在冷原子束出射方向上，还置有载有彼此电流方向相反的四根成锥形排列的直导线，从而原子出射时将在磁场的作用下，不会沿横向膨胀而向前射出；便得到了出射速度低的、通量较大的、横向速度非常小的连续冷原子束；同时在冷原子束的出射方向上，设置有与原子束垂直的激光束，用于原子束的态制备，实现态一致的出射冷原子束。

PRT considers all incident lighting from the upper hemisphere on each point of the surface resulting in smooth shadow. In this method, by considering the way light source is blocked by other objects and how it reflect on object surfaces, one can create self-shadowing and self-interreflection effects.

PRT因为考虑物体每一个表面点单独受到四面八方光线的影响，因此所呈现的明暗效果非常平滑，同时此光照技术也能够考虑每一个表面点光源被物件其他部分遮住的情形以及受到其他物件反射光线之影响，因此能够表现从来无法以及时运算呈现的自身阴影与反射光。

In order to draw a photorealistic surface, Bidirectional Texture Functions, a 6D texture function which extends Bidirectional Reflectance Distribution Function to include the self-shadowing, self-occlusion and inter-reflection effects, has been mentioned frequently in recent years. Its main drawback is its massive data size. To solve this, Spatial Bidirectional Reflectance Function techniques compress BTFs into reflectance model parameters. However, SBRDF cannot producethe self-shadowing and self-occlusion effects in real-world surface geometry. This work is aimed to this drawback. I find how self-shadowing and self-occlusion affect the surface by additional physical-based analysis. And I rely on two physical phenomena to divide self-shadowing and self-occlusion into two independent effects. First, self-shadowing is view independent. Second, self-occlusion is independent of lighting direction changes. After these analyses, I use SBRDF and additional self-shadowing and self-occlusion I found to render a photorealistic surface as non-compressed BTFs doing.

为了把物体表面呈现的更真实，六维函数BTFs ( Bidirectional Texture Functions)目前已经被使用的相当频繁，但BTFs的资料量实在太大而没办法直接使用，为了解决资料庞大的问题，传统的SBRDF以逼近光反射模型参数，来达到资料压缩的效果，但是SBRDF对於表面的凹凸所产生的阴影及遮蔽，不能达到逼真的呈现，为了改善这个问题，我们选择从物理方面，找出资料中阴影和遮蔽等属於表面几何的资料并去除，使参数更正确，同时利用两个物理现象去区分阴影及遮蔽为两个互不干涉资料，第一是阴影不会因视角不同而改变，第二是遮蔽不因光线方向不同而改变，经过这些分析，我可以利用SBRDF加上附加的阴影及遮蔽两种独立的效应，来达到彷佛跟未压缩过的BTFs一样的真实绘图。

Applying a wax, whether it's synthetic, natural or a blend of both, to a neglected surface that has not been properly cleaned and then polished, will merely act to seal or lock the contaminants to the finish, and will do nothing to improve, or remove the other defects and in most cases will only marginally improve gloss, shine and reflectivity.

将合成蜡或天然蜡或天然合成蜡上於未被清洁的肮脏表面时，只会把脏污密封或锁在烤漆表面，这将没办法改善或移除其他的缺损，在大部分的情况下，它只会稍稍地增进色泽、光泽和反射能力

By pretreatment with ruthenium red (RR, 100 1 μmol/L), an antagonist of vanilloid receptor subtype 1 (VR1), the above effects of CAP on carotid baroreflex were abolished.

2用香草酸受体亚型(vanilloid receptor subtype 1， VR1)阻断剂钌红(ruthenium red， 100 μmol/L)预处理后，CAP的上述反射效应即被阻断。

Celebs are still the major force on the list, However, some undersung grass-root bloggers do have what it takes to make them like a real star, so some star-makers are scouring around, find some and give those fresh faces' star career a kicks-tart, or make them at the frontpage of tabloids, or help them steal the spotlights from others super nova in the celebrity universe.

Once considered a false dawn , this triangle of light is actually Zodiacal Light , light reflected from interplanetary dust particles .

一度被视为虚假的黎明，这个三角形的光其实是黄道带光，来自星际尘埃粒子的反射。

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。
