Vidicon collect simulate image in period of time and send to computer or DSP chip through video collection card digitlization,use computer to gain eyewinker and process digital image processing:using image area segment and boder measure to calculate area and perimeter;using image smoothness to wipp offthe infection of yawp;using dynamic background and image suited technology to overcome the infection of ray;calculation the parameter of eyewinker(area, perimeter,round measurement, proportion characer and invariant monent),using least norm to design the linearity classify parts,using image matching technologyto classify eyewinker,and to judge whether the eyewinker is harmful to diff background,if the eyewinker satisfy the character require of harmful object ,system will auto-stsrt alarm device. If there ia not have found any eyewinker, Vidicon will collect new simulate image and make processing.

本设计是将摄像机或高频头采集到的模拟图像经过视频采集卡数字化后送入计算机或DSP芯片，利用计算机对采集到的一定时间段内的图像进行异物获取，并对异物图像进行数字图像处理：利用图像区域分割和边缘检测以便进行面积和周长的计算，利用图像平滑去除噪声的影响，利用动态背景运动检测法和图像配准技术克服光线的影响，并通过异物的各类参数（如面积、周长、圆形度、比例特征和不变矩等）的计算，采用最小范数分类法设计了线性分类器，利用图像匹配技术对异物进行分类，从而判断异物是否有害，针对于不同的背景，若异物满足有害物体的特征要求，则认为物体有害，自动启动报警装置，如果没有发现有害异物则新摄入的图像将取代前一时间段的图像再进行图像处理。

Based on the traits of the aspherical lens, the sunlight was focused on a very small spot, and then it was transferred into a plastic fiber by an aspherical lens and a selfoc lens. A formula for calculating the optimal length of selfoc lens is presented. The optimal assembly of the aspherical lens and selfoc lens was implemented by the aid of this formula. Therefore, sunlight is coupled into a plastic fiber efficiently.

根据非球面透镜垂轴球差小的特点把太阳光会聚到很小的光点，再利用长度约为1/4节距的自聚焦透镜改变光线的数值孔径使其满足光纤的数值孔径，通过一个计算公式来计算最佳的自聚焦透镜长度，实现非球面透镜和自聚焦透镜的最佳组合，把太阳光以较高的耦合效率耦合进塑料光纤。

However, the image-retrieving environment is so complicated, such like from a nature object to a variety of objects, from a light environment to a dark environment, or from a nature light to a daylight in office, the properties of objects, and the varieties of light sources and light intensities. These complex external image-retrieving environments let users can not get an accordant image quality. Such under a tungsten lamp, the image appears yellowish and reddish; under daylight in office, the image becomes greenish and bluish.

CCD Camera面对的是复杂的取像环境，从自然景物到各式各样的景物，从光亮环境到灰暗环境，或从自然光到办公室日光灯、景物的特性、光源的种类及光线的强弱，这些外在复杂的取像条件及变因往往让使用者无法得到相当一致的影像品质，如在钨丝灯下拍摄的影像，将产生偏黄、偏红效果的影像；在办公室的日光灯下将产生偏绿、偏蓝效果的影像。

Chapter 20 The Cemetery of the Chateau D'If 第二十章伊夫堡的坟场 ON THE BED, at full length, and faintly illuminated by the pale light that came from the window, lay a sack of canvas, and under its rude folds was stretched a long and stiffened form; it was Faria's last winding-sheet,--a winding-sheet which, as the turnkey said, cost so little.

借着从窗口透进来的一线苍白微弱的光线，可以看到床上有一只平放着的粗布口袋，在这个大口袋里，直挺挺地躺着一个长而僵硬的东西。这个口袋就是法利亚裹尸布，正如狱卒所说的，这的确不值几个钱。

Spearman finally broken in the house, hiding in his military officer in Germany before the playing of Chopin's first Ballade, the bunch of moonlight straight from Spearman shed to the top of the left shoulder, the kind of light symbolizes a kind of sacred; have a bunch of astigmatism in the German officers to fight the front, and this light treatment, this made us think he is like a penitent sinner.

在斯皮尔曼最后藏身的破房子里，在他在德国军官面前弹奏肖邦的第一叙事曲时，一束月光径直的从斯皮尔曼左边的肩膀上方洒下来，那种光象征着一种神圣；还有一束散光打在德国军官的正面，而这种光线的处理，却让我们觉得他像一个正在忏悔的罪人。

The results are bound to help the search for life on other planets, because it might be possible to identify former--or even existing--habitats by detecting the telltale spectrographic signatures of these minerals in light from distant planets .

这些成果必然有助于搜寻其他行星上的生命，因为在遥远的行星上，在光线的照射下，矿物的光谱信号可以提供证据，通过探测这种信号，有可能识别出以前的、甚至现有的生命栖息地。

Musashi, however, was not there. When officials found him he was still asleep! He was woken up and, despite exclamations to the contrary, took his time breakfasting before setting out towards the Island.

同时武藏的剑术是否高一直是无聊的日本男人争论的焦点，吉川英吉巧妙的将武藏的胜利描述成靠心理战术和对地形光线的巧妙运用，而不是简单的以武艺决高下。

In scenes televised nationwide, rescuers cried as the soot-covered men - stuck underground since Sunday, March 28 - were brought out, some barefoot and others with cloth-covered eyes to protect them from the light after days in pitch dark of the Wangjialing Coal Mine in Shanxi Province, the heart of China's coal country.

面向全国转播的电视镜头显示，当这些一身乌黑的矿工被抬出地面时，救援人员痛哭流涕。矿工们是在3月28日被困的，地点位于中国产煤大省山西的王家岭煤矿。他们被抬出来时，一些人赤着脚，其他人的眼睛用布罩遮住，防止他们在漆黑之中呆了多日后受到光线的伤害。

First firing of raw materials are usually basic glaze frit, in the process of production need to add metal oxides, metal ions is also a special color of the enamel glaze color, or as a gel, or suspension-like particles of the dispersion or absorption of light and color, for example, cobalt oxide blue or purple, blue green copper oxide, cobalt oxide copper oxide mixture is significant blue, red cuprous oxide, nickel oxide in the potassium content of the glaze was red, in the sodium yellow glaze of green, if used alone was brown iron oxide, cobalt oxide and manganese dioxide are combined black or dark brown.

通常是先将原料烧成基本釉的熔块，在制作的过程中再加入需要的金属氧化物，也就是以金属离子特具的颜色而使珐琅釉呈色，或成为胶状，或悬浮状的粒子对光线的色散或吸收而呈色，例如氧化钴呈蓝或紫色、氧化铜呈蓝绿色、氧化铜混和氧化钴则显青色、氧化亚铜呈红色、氧化镍在含钾之釉中呈红色、在含钠之釉中呈黄绿色，又如氧化铁单独使用呈褐色，与氧化钴及二氧化锰合用则呈黑色或黑褐色。

But the faint pinpricks of light from far-off worlds have captured the public's imagination and will give astronomers new clues to what those distant planets are made of and how they were formed.

但从遥远的世界发出光线的微弱小孔已经引发了公众的想象力，将为天文学家确定这些遥远的行星是什么做的、如何形成的提供新的线索。

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。
