光线

Based on theories of geometrical optics and electromagnetic wave promulgation, models of three status of aqueous foams transit by light were set up, and the situations of mono- and double- layer unassimilated, assimilated and electric solid infusible materials were investigated for the changes of orientation, path and energy distribution of ray.

基于试验结果，利用几何光学原理和电磁波传播理论，建立了水基泡沫三种状态(来源：AcfB2d2dC论文网www.abclunwen.com)下的消光模型，通过理论分析和数值模拟，研究了单层界面无吸收、双层界面无吸收、有吸收和含导电性固体不溶物情况下的光线传播规律，从光线传播方向和能量的变化方面，揭示了水基泡沫消光的机理及其对目标探测和甄别的影响。

The light emitted from a Keplerian ring around the objects with strong gravitational field should be affected by Doppler shift, gravitational redshift and deflection of light. The line profiles for a faraway observer are dominated by these effects. In this paper the precise solutions of line profiles for the Keplerian rings in the Schwarz-schild case have been obtained by means of the kinetic equation for photons.

对于一个围绕强引力场物体作开普勒运动的环状发光物，它所发射的光线要受多普勒频移，引力红移和光线偏折等效应的作用，这种作用决定了远处观察者所看到的谱线轮廓，本文利用光子输运方程方法，求出在Schwarzschild度规中的开普勒环所发射的谱线的轮廓的精确解。

It is difficult to be simulated and analyzed due to the excessive surfaces, complex structure and locomotory parts in zoom lens. All the transmission planes taken as the partial reflection and partial transmission planes were simulated with ASAP（advanced system analysis program）and the stray rays on "dangerous surfaces" which easily generate the ghost images in zoom lens were analyzed. Based on it, the zoom lens was optimized and the quality of image was improved by changing the curvature and refractive index of the second reflection planes.

利用ASAP软件模拟每个透射面作为部分透射、部分反射的表面，对变焦光学系统非轴上光进行分析，模拟出变焦系统的光学元件表面和光机内壁，实行实际光线追迹，然后以像面为研究对象，进一步实施实际光线追迹，模拟出全部散射光在像面上的能量分布，找出鬼像形成的原因，并在此基础上通过改变二次反射所在面的曲率或改变所在面的折射率两种方法对变焦光学系统进行优化，减小鬼点数目，以提高系统的成像质量。

But instead of the darkness, and the thick and mephitic atmosphere he had expected to find, Dantès saw a dim and bluish light, which, as well as the air, entered, not merely by the aperture he had just formed, but by the interstices and crevices of the rock which were visible from without, and through which he could distinguish the blue sky and the waving branches of the evergreen oaks, and the tendrils of the creepers that grew from the rocks.

唐太斯本来以为洞里一定很黑暗，空气中一定带着浓重的腐臭味，但到了里面，他却看到一片浅蓝色的昏暗的光线，这种光线，象空气一样，并非只是从他刚才挖开的洞口那儿射来的，是从岩石的裂缝里穿进来。这些在洞外是看不到的，但到了洞里，却可以透过它们看到那蔚蓝的天空，看到那些长在石缝里的常春藤，卷须蔓和野草的枝叶。

For rickets in children, should be served morrhuate usually have more exposure to sunlight, including the outdoor light and the reflected light, but not across the glass "sun."

对于佝偻病患儿，应加服鱼肝油，平时多接触日光，包括户外光线及反射的光线，但不要隔着玻璃&晒太阳&。

Poly(1-alk-1-viny pyridinium halides) have also been shown to be good negative electron beam resists with sensitivities as high as 5uCcm-2 in a 20kV electron beam and line widths as low as 0.3um.

波河 (单一 alk 的-1-葡萄树的 pyridinium 卤化物)也已经被显示很好否定的电子光线以敏感 20 仟伏电子光线和线宽度的像 5uCcm-2 一样的高度像 0.3um 一样的低点抵抗。

His snorting throws out flashes of light; his eyes are like the rays of dawn.

他打喷嚏、就发出光来。他眼睛好像早晨的光线。〔光线原文作眼皮

Based on the technique of PIV,We calculated the light intensity of the bubble interface and discovered that the intensities of lighr reflected or refracted twice succeedingly abide by the rules of geometric series , and the light will disappear after reflecting or refracting 4 times by the bubbles.

基于粒子成像测速的流体可视化技术，根据菲涅耳公式计算了入射到水中气泡界面的光强，得出点光源连续两次反射或折射的光强具有等比数列的规律，光线在气泡界面反射、折射4次就变成完全偏振光且光线几乎消失。

They generally work reflectively when external light levels are high, and transmissively in darker environments via a low-power backlight.

当外部光线很足的时候，该LCD按照反射型工作，而当外部光线不足的时候，它又能当作透射型使用。

You can see some, but then if you go up high in the mountains, up to McCall, and you have all the lights out, that's what it will be like once we undock from station and we can turn all our shuttle lights out, and also for the station folks they can turn all their lights out.

你可以看见一些，但如果你往山顶的高处爬，直到与McCall一样高时，光线已经不再影响了，这正如我们空间中解放一样，我们可以撇开所有的灯光，同时对于空间站的人来说他们可以关闭光线。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
