光线的

Color The achromatic color of maximum lightness; the color of objects that reflect nearly all light of all visible wavelengths; the complement or antagonist of black, the other extreme of the neutral gray series. Although typically a response to maximum stimulation of the retina, the perception of white appears always to depend on contrast.

白色：光亮度最大的一种无色；能反射几乎肉眼可见的所有波长光线的物体颜色；黑色的互补色或对抗色，中性灰色系列的另一种极端色，尽管白色通常是对视网膜所受最大限度刺激的反应，人们对它的感知却总是显得依赖于对比

Imperfections in glass appear more severe than they actually are because of the glass' transparency. Blemishes appear magnified. Diamondite Glasswork Restorer gently smoothes the edges of fine scratches and polishes away mineral deposits to leave a level surface that reflects light evenly.

因为玻璃是透明的，所以玻璃表面上的瑕疵是非常容易被看见的，Diamondite玻璃抛光剂可以温和的磨平细微刮痕的边缘和抛除矿物沈积，使用后让玻璃呈现均匀反射光线的平整表面

In the process of exploring the universe, one of the most important information sources is obtained by studying the frequency change of rays that come from distant illuminant.

我们在探测宇宙的过程中最重要的信息来源是通过研究遥远光源发出的光线的频率的变化得到的。

Color filters are very important components for optical equipment. Basically,color filters are made of high-density glass or isinglass.

彩色滤镜为光学装置一极重要的器材，基本上，滤镜是一种由高质量玻璃或明胶制成的光学平面物体，可对全光谱中某些固定的波段的光加以过滤筛选，以改变光线的颜色，强度与品质。

The coating of this binocular, made in 2000, must be state of the art. Another factor may be a physiological one: The human's eye is optimized for daylight use. After sunset, the spectrum of the residual light is shifting toward the short wavelength side.

另一个影响因素是生理上的：人类的眼镜是为白天使用优化过的，日落后，残留光线的光谱移向短波长那边，IOR的轻微偏黄能补偿这种影响。

In some sense,light damage depends on the amount of rhodopsin available for bleaching during light exposure.

摘 要：视紫红质是感光细胞中的一种视色素，在光线的接收和视觉电位的产生方面具有重要的生理作用，由视紫红质介导的过度光信号传导是光性视网膜变性的主要原因。

Because the image wraps around almost a full 360 degrees, the angle of the lighting becomes downright surreal ; notice how the photographer's shadow seems to stretch towards the Moon, and how the shiny ESO 3.6-metre telescope in the foreground appears to reflect light from a source located opposite the Moon.

由于这是360°全景图，光线的角度是超现实的：图中的影子竟然朝向月亮延伸，而最显眼的ESO3.6米望远镜的反光效果恰似光源在月亮的正对面。

A new self-adaptive background approximating and updating algorithm based on optical flow theory is first presented in this paper.

在光流场等技术的基础上，提出了一种自适应背景逼近更新方法，以适应光线的变化以及噪声的影响；根据彩色差值模型计算当前帧图像和当前逼近背景图像的差分图像；并引入Gauss模型实现了运动目标的自适应阈值分割。

Another darkness was closing in as surely, when the church bells, then ringing pleasantly in many an airy steeple over France, should be melted into thundering cannon; when the military drums should be beating to drown a wretched voice, that night all-potent as the voice of Power and Plenty, Freedom and Life.

既然人类知识已经可以分析出光线的构成，那么，更高级的智力必将能在我们这个地球的微弱的光亮中读解出它每一个负责人的每一种思想和行为、每一桩罪恶和德行了。

For hundreds of millions of years, turtles have struggled out of the sea to lay their eggs on sandy beaches, long before there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to hand-carry the hatchlings down to the water's edge lest they become disoriented by headlights and crawl towards a motel parking lot instead.

在数亿年前的时间里，海龟一直在挣扎着离开大海道海滩上产卵，时间远远遭遇自然纪录片的赞扬，或全球定位通讯卫星和海洋生物学家的追踪，又或者志愿者们用手把幼龟放在海边以避免它们受到光线的影响迷失方向，爬向汽车旅馆的停车场。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
