底片

In photography, the essential light sensitive coating on ph otographic film comprising gelatine and silver salts.

在照相技术中，覆盖在照相底片上的由胶和银盐组成的感光物质。

In this way you geta negative imprint of the surface.

这样你就得到了被拓物体表面的底片。

It will also increase the halo effect on the highlights, and the "#~"film graininess.

它也会增加亮部的光晕效果，和底片颗粒度。

Using ink-jet or laser printer produced the blackness often is not enough.

用喷墨或激平打印机制息的底片的暗量凡是是不敷的。

Both of the ESD were proportional to kVp 2.2 to kVp 2.5 and were linear proportion to mAs. Inverse square law exists in the relationship of focus-film distance, FFD, and ESD. The impacts of field size and patient thickness to ESD are negligible. Optimized operating condition is chosen to improve the diagnosis rate and to reduce the patient dose. The ESD, 0.12±0.06 mGy, performing the optimized operating condition of chest x-ray examinations, is less than both values of reference doses recommended by NRPB and IAEA.

研究结果发现，入射表面剂量随操作条件而变，以相同的条件照射，三相位X光机所造成表面剂量大约是单相位X光机的1.9倍；入射表面剂量与kVp的2.2至2.5次方成比例，与mAs约成线性正比，与焦斑至底片距离的关系大约符合平方反比定律；照野面积及身体厚度虽会影响表面剂量的大小，但其程度远低於kVp及mAs的影响。

Film and Camera formats, Built-In Light Meter, etc.

底片和相机的形式、内建测光表…等。

You can get rid of the unwanted detail by masking out the bottom of the negative during processing.

你可以在洗印照片时遮住底片的底部以去掉那不需要的部分。

He was soon working for Condé Nast as a photoengraver working with color separations and half-tone negatives.

他很快工作康德纳斯作为一个分色和半色调底片工作photoengraver。

Hence, it is fair to say that NEG models have so far the scientific status of examples.

因此，它是公平的说底片模型至今科学地位的例子。

Interviewer: What do the 'neg' cutters do?

底片剪辑人员是作什么的呢？

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
