暗视觉

But the miners helmets with black, obviously does not meet safety ergonomics principles, because the shaft lighting poor, the black miners cap was not obvious in the chiaroscuro, theLikely due to blurred vision and security incidents.

但矿工安全帽采用黑色，显然不符合安全人机学原则，因为矿井下照明较差，黑色矿工帽在明暗对比不明显时，容易由于视觉模糊而发生安全事故。

Purpose: The single oscillatory response in complete dark adaptation and the effect of mesopic illumination were studied in order to investigate the behaviour of the neuronal adaptation system as reflected in the oscillatory potentials of the electroretinogram.

本研究的目的在于研究暗适应下的单次振荡响应和中间照明亮度的影响，通过分析视网膜电图上的振荡电位，从而研究神经视觉系统的适应过程。

Of our famed rods and cones, the two classes of light-sensing cells with which the retina at the back of each eye is supplied, the rods do the basics of vision, of light versus shadow, tracking every passing photon and allowing us to see by even a star's feeble flicker, though only in gunmetal shades of black, white and grim.

在我们眼球后面的视网膜上有锥状和柱状两类感受光亮的细胞。柱细胞承担视觉的基本操作，分辨明暗，跟踪光子，使我们透过那怕只是由黑白蓝调出的铁灰色，也能看见遥遥星空的闪烁。

Although we tend to think of animation as implying object motions, the term computer animation generally refers to any time sequence of visual changes in a scene.

尽管我们在考虑动画时暗指对象的移动，但术语计算机动画通常指场景中任何随时间而发生的视觉变化。

Therefore, when you deal with colorful scanned in black and white will not only match the crime scene embody the white and black object hierarchy of the Zodiac, and outstanding visual contrast of light and shade.

因此，扫描时处理好彩图中的白和黑，不但能逼真表现各种白色和黑色物体的层次质感，且能突出视觉上的明暗对比度。

Breed of terrier known for its superb senses of sight, hearing, and smell while hunting fox, weasel, European polecat, otter, badger, rat, and other small game; medium-length coat is slightly curly, hard, wiry, and dense; it is black and tan and often comes in a saddle pattern; ears are set high on head and fold forward in a V-shape; tail is thick, short, and carried erect; eyes are small, dark, and sparkling; adult stands 22 23 in.(56 58 cm) tall at shoulders and weighs 40 50 lbs (18 23 kg); dutiful and courageous demeanor yet with a sweet disposition toward children and its master; served the Red Cross during World War I and World War II to locate wounded soldiers and carry messages; developed by Yorkshire hunting class to be used on river-valley hunting jaunts

艾尔谷犬是小猎犬的一支，因其在追踪狐狸、黄鼠狼、欧洲臭鼬、水獭、灌熊，老鼠，和其他小家伙中表现出来的卓越的视觉，听觉和嗅觉而为人所知；适中长度的毛发轻微的卷曲，坚硬，结实而密；耳朵长在脑袋上部，向前笼罩成"V"型；尾巴厚、短、坚挺；眼睛小、暗、机智；成年站立肩高56—58厘米，重18—23公斤；举止顺从、无畏，对于主人和孩子有着可爱的个性；跟随红十字会服务于第一、二次世界大战搜寻伤员，传递信息；艾尔谷小猎犬是由约克郡的猎户改良出来，用于在河谷中的短途打猎旅行。

Since its discovery, vitamin A has been shown to be pivotal in several bodily functions: formation of "visual purple" which allows us to see partially in low light; maintenance of healthy vision and proper eye function; repair and maintenance of epithelial tissues, especially those of the skin and mucous membranes; maintenance of the endocrine system, especially the thyroid gland; proper utilization of dietary proteins; and stimulation of the thymus gland, a major part of the immune system.

由于其发现，维生素A已被证明可在几个举足轻重的身体机能：形成"视觉紫色"让我们看到部分在光线较暗的；维护健康的理想和正确的眼睛功能；修理和保养上皮组织，尤其是那些对皮肤和粘膜膜；保养内分泌系统，特别是甲状腺；适当利用膳食蛋白质类；和刺激胸腺，一个主要部分免疫系统。

From the light green into Chenopodium, and then Anzi, the completion of the outdoor to indoor transition, corresponding to the human visual space for the natural reaction.

从淡绿转化为灰绿，然后暗紫，完成室外到室内的过渡，对应了人的视觉对空间的自然反应。

In the suboesophageal ganglion, 5-HT/TPH-like immunoreactive neurons (ca.15) mainly distributed in the lateral and ventro-lateral area, with processes projecting into the suboesophageal ganglion neuropil.

结果表明，5-HT作为经典的神经递质在昆虫的视觉信息处理过程中发挥着重要的调节作用，且主要通过远距离的广域神经调节模式来控制昆虫的昼夜节律行为，并在特定区域和GABA协同起作用；昆虫视觉系统中5-HT的含量还可能与其明暗适应的生理调节方式密切相关。

The 2-D bar code can be read from a front side or a rear side of the plate using a bright-field or dark-field vision system.

该2-D条形码能够从钢板的前侧或后侧使用明视场视觉系统或暗视场视觉系统来读取。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
