光像

Imaging quality of a single mirror and two mirrors in the case of grazing incidence is discussed. The focal length, field obliquity and diaphragm position of KBA microscope are analyzed.

详细分析掠入射情况下单镜及双反射镜的成像特性，对组成KBA显微镜的反射镜在掠入射条件下的焦距、视场倾斜、光阑位置等进行研究。

The first sign that this was about to happen came through the post—a terrifying document from a gunsmith in Vaison-la-Romaine, offering a complete range of artillery at preseason prices.

其中一位男士藏有5支口径不等的来福枪，而另一位则有8支上了油、抛了光的长枪，赫然陈列在餐厅墙壁的框架上，像一件件致命的艺术品。

This is where they do things that are technically illegal–like document forgery and computer hackery and all kinds of other shady stuff.

这是他们用来进行违法加工的场所——像是伪造证书或电脑黑客等所有见不得光的事。

The longitudinal conjugated property of ideal optical system ;2. Starting from the principle of photograph formation by an ideal optical system , this paper derives the formulas of field depth and hyperfocal distance.

本文从理想光具组成像原理出发推导出景深和超焦距的公式，物理思想明确，并结合公式绘出了景深与有关参量的直观图，摄影者容易理解和掌握。

Some scientists have proposed that the presence of increasing levels of ultraviolet light with elevation may play a role, while browsing and grazing animals like the ibex may be another contributing factor.

一些科学家有被提议的出现逐渐增加的水平紫外线的光与海拔可能游戏一个角色，当浏览的时候和放牧像野生山羊的动物可能是另外的有助于因素。

Standing on the snow-covered plain, as if in a pasture amid the hills, I cut my way first through a foot of snow, and then a foot of ice, and open a window under my feet, where, kneeling to drink, I look down into the quiet parlor of the fishes, pervaded by a softened light as through a window of ground glass, with its bright sanded floor the same as in summer;there a perennial waveless serenity reigns as in the amber twilight sky, corresponding to the cool and even temperament of the inhabitants.

站在积雪的平原上，好像在群山中的牧场上，我先是穿过一英尺深的雪，然后又穿过一英尺厚的冰，在我的脚下开一个窗，就跪在那里喝水，又望入那安静的鱼的客厅，那儿充满了一种柔和的光，仿佛是透过了一层磨砂玻璃照进去的似的，那细沙的底还跟夏天的时候一样，在那里一个并无波涛而有悠久澄清之感的，像琥珀色一样的黄昏正统治着，和那里的居民的冷静与均衡气质却完全协调。

You, like a candle, a weak light illuminated the ocean of knowledge.

你们，像一支蜡烛，微弱的光照耀知识的海洋。

And a standard hyperhemisphere immersion lens with high refractive index is put behind the object lens to satisfy the receiving of a detector with smaller photosensitive surface.

弯月型负透镜在前，具有平衡像差和棱镜的偏向作用；物镜后放置高折射率标准超半球型浸没透镜，满足小光敏面探测器接收。

The corona's rays flash out in a brilliant fan that has wispy spike-like rays near the Sun's north and south poles.

光环带的光束像一把流光折扇，在太阳的南北两极附近形成纤细的辐射线。
