光像

Unified explanation of the effects due to Talbot and Montgomery effect is presented in optical path difference between diffraction spatial frequency spectrums.

从成像过程中各衍射频谱分量的光程差，给出了Talbot效应和Montgomery效应的统一解释。

A complete explanation for Talbot and Montgomery effect is presented by studying the optical path difference of each diffraction spectral component formed in the process of imaging.

从成像过程中各衍射频谱分量的光程差出发，给出Talbot效应和Montgomery效应的统一解释。

If I wanted to convey both magic and ordinariness, and I did, I needed an image which would put the light of that first window into the context of the downright and plainspoken image of yellow butter.

如果我既想表达魅力又要突出平凡，我就需要一种镜像可以把第一扇窗户的光，引入到彻底而又直白的黄色奶油上面－我也是这么做的。

First, we extract the boundaries between two different materials by weighting with gray-level gradient,and only voxels on these boundaries participate in the generation of each image, so it drastically reduces the rendering time. Second. We think the voxels on boundaries as the mixture of different materials,so in every voxel there is a surface. We use the oriented cube-interpolation technique to get the intersection point of viewing orientation and the surface in the voxel, then compute the surface normal of the intersection point. We use the normal to shade the voxel in order to improve the image quality.

首先，采用灰度梯度加权提取出三维数据场中不同物质间的边界，根据显示的需要只对这些边界上的体元赋予相应的阻光度并进行光亮度合成计算，因而可大大减少计算量，提高显示的速度；将边界上的体元作为不同物质的混合体，采用与方向有关的三线性插值来计算视线方向与体素内等值面的交点，根据交点的法向量进行光照效应计算以提高显示图像的质量；最后用投影成像法显示最终的图像。

FRIAR LAURENCE The grey-eyed morn smiles on the frowning night, chequering the eastern clouds with streaks of light, and flecked darkness like a drunkard reels from forth day's path and Titan's fiery wheels: Now, ere the sun advance his burning eye, the day to cheer and night's dank dew to dry, I must up-fill this osier cage of ours with baleful weeds and precious-juiced flowers.

黎明的曙光含笑地送别眉头紧皱的月夜，用光线在东方画出鱼鳞般的云霞，向黑暗撒下用光织成的鱼网；黑夜像晕头转向的醉汉，被太阳的火轮追赶出白昼的轨道。现在，太阳神还未圆睁火红的眼睛，白昼还未欢腾，露水还未晒干；我必须用苦涩的野草和鲜艳的花朵盛满我这个柳条筐。

"It is far more sensitive than radiography for bone erosion in patients with early rheumatoid arthritis, and can detect pre-erosive features, such as osteitis and synovitis, along with tendonitis and potentially other MRI features that can be used to predict which patients will go on to severe destructive joint damage and irreversible functional disability," Dr.

Peterfy医师进一步指出，对於早期类风湿性关节炎病患而言，MRI在骨质糜烂的诊断上，远比X光摄影灵敏许多，且可侦测到糜烂前的特徵；像是骨炎与滑膜炎、连同肌腱炎与可用於预测严重破坏性关节损害及无法恢复的功能障碍，能一开始就向病患展现准确的预测，进行一个有效率的病患管理是非常重要的。

Against the flesh black paintwork, the bare white splintered shaft stood out jarring and ugly, like the millet stalks blatantly sticking out from under a fine paper figure which hasn't yet had its legs pasted on.

崭新黑漆的车，把头折了一段，秃碴碴的露着两块白木碴儿，非常的不调和，难看，像糊好的漂亮纸人还没有安上脚，光出溜的插着两根秫秸秆那样。

March 20, 2003 Chest x-rays can be read by pediatric critical care physicians as reliably on bedside personal computers as on radiology work stations except in the presence of diffuse disease, according to the results of a paired comparison study published in the March issue of Pediatric Critical Care Medicine .

March 20， 2003 -根据一篇发表於3月份「小儿重症加护医学（Pediatric Critical Care Medicine）」期刊的研究结果显示，除了弥漫性肺疾之外，小儿重症加护医师也可以利用放射线工作站来读取患者的胸部X光摄影，就像床边个人电脑一样可靠。

His theory is supported by evidence found through x-ray examination and infrared reflectography analysis of the painting and its panel.

透过X光检查和红外线反射成像技术分析画及画板后，更支持他的理论。

For the requirement of high efficiency light emitting diode luminaries and the characteristics of automotive headlamp exit beam,based on non-imaging optical theory,a theory model for new type LED parabolic reflector optimal design is established to maximize the utilization of light energy of the reflection cup and to realize the asymmetric light intensity distribution of the headlamp exit beam.

针对当前发光二极管灯具的高效率要求和汽车前照灯出射光束特点，根据非成像光学理论建立了新型LED抛物反射器优化设计的理论模型，实现了反射杯光能利用率的最大化和前灯出射光束的不对称光强分布，进而依据该模型设计了新型反射式LED汽车前照灯光学系统。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
