A: For Leica M39 is OK. but the image circle will not reach 43.7 mm which is full 24x36 mm. This lens projects 32mm image circle only. You got only Half frame.

谢谢大家的解说，小弟前两天拿了这颗镜头给阿基师看过，答案是没办法，过两天又要出国回到工作岗位，就先放著再说了。

The properties of a rotationally symmetric parabolic X-ray lens are studied theoretically and numerically in this paper.

本文给出了旋转轴对称抛物面型X射线组合透镜的理论研究成果。

But looked at through the lens of greenhouse gas accounting, they are living smokestacks, spewing methane into the air.

但若以计算温室气体的角度看来，这些牛猪活像冒气的烟囱，不断向空中喷出甲烷。

The ratio of the focal length to the diameter of a lens system.

相机镜头直径焦距比。

This 90mm telescope is the first fluorite APO refractor in the market,thanks to the flourite lens design, at f/11 focal ratio, the secondarychromatic abberation is eliminated.

90毫米的望远镜是第一萤石载脂蛋白折射在市场上，由于flourite镜头设计，在f/11镜头协调比例，二级色abberation是消除。

The rotary connection can be carried out in free space and hi-direction transmission of optical signal can be performed. Through analyzing the design principle of the optical structure and optical path calculation, it is found that when the ratio between the focal lengths for two lens is 20~50 and off-axis distance is in the range of 4~10mm, the interference will not be occurred between two optical channels and signal transmission can be lasted.

在自由空间可以实现旋转连接并实现光信号的双向传输，通过分析该光学结构设计原理和光路计算，发现每组透镜中两个透镜焦距之比为20-50，离轴距离为4-10mm范围时，才能保证光通道之间不发生干扰且信号持续传输。

In order to obtain 266nm UV laser, we use a type-I phase match BBO crystal(θ=47.6°) pumped by the green laser above and a focus lens. the spectrum of 266nm UV laser is measured by a UV spectrometer. But we can not obtain the output power for absence of available spectroscopes.

在高功率、高重复频率绿光激光器的基础上，采用I 类相位匹配(θ=47.6°)的BBO 倍频晶体，实验中测得了266nm 激光光谱，但由于缺乏有效的分光措施无法测得输出功率。

I appraised the light, adjusted the lens setting and distance, locked a bulb in the flashgun

于是，我对好光，调好焦距，又安了一个闪光灯泡，然后举起像机，将这一场面在取景器中定格。

I appraise d the light, adjusted the lens setting and distance, locked a bulb in the flashgun, raised the camera and composed the scene in the viewfinder

于是，我对好光，调好焦距，又安了一个闪光灯泡，然后举起像机，将这一场面在取景器中定格。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
