快门

The main principle of this technique is to control sensitization time of photographic plate by light impulse instead of shutter.

高速频闪摄影技术的主要特点在于：用光脉冲代替相机快门，以控制底片的感光；在光脉冲时间非常短(本文最小光脉冲宽度可达8μs，其技术指标代表目前国内的最高水平)的情况下，达到对高速运动的流体"冻结"而拍照、观察的目的。

Interposed between the lamp and graticule unit was a hemispherical shutter, pivoted and rotated by a lever, which, when rotated, shrouded the ring, giving a spot graticule only.

在灯泡和分划单元之间插入了一个半球状的快门，由一个杠杆操纵它转动，它一转，就会遮住光环，只显示一个点状分划（就像Beamont所作的改进一样）。

It lets me do things I never could, like jump into a dark, abandoned building without a tripod, shoot away at f/2.8 and high ISOs on a D3, and get out with excellent photos for which I don't need to make any excuses.

它让我能做到以前从未做到的事情，如遁入黑暗的废弃的建筑里，不拿三角架，用D3在高ISO下开按动快门。并且能出很好的片。

"Flash bounced over my left shoulder. Note that there is NO direct flash, and hence no flash shadow."

下面这张图里面，作者是把闪光灯打在了左边，同时采用了1/250的快门速度，这样使得新娘身后的窗户也能正常曝光。

When I install the film and press the shutter release, nothing happens, I think it's broken.

我装好底片，按快门时，它一点反应都没有，所以应该是坏掉了。

After the sound of the shutter release, the large charge of successful capture is coming up.

快门响过，随之而来的是一种捕获成功的快感。

I somehow managed to release the shutter at the crucial moment.

我在关键时刻不知道如何处理按动照相机的快门。

You must not jerk the camera when you press the shutter release button.

你按快门开启按钮时，不能猛按照相机。

By using the separately sold release switch, the shutter can be release d from a distance.

利用单独出售的释放开关，可于较远距离下释放快门。

Now slowly press the shutter release button until you see the red over exposure lamp.

现在慢慢地按下快门释放按钮，直到看到红色过度曝光灯。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.

在大学的三年的学习生活不仅给予我自身的充实，更重要的是磨练和培养了我较强的自觉能力和严谨，踏实的作风以及不怕困难的精神，对未来充满了信心！

As the first volcanoes erupted, one of the gases that bellowed out was steam.

在第一批火山喷发时，喷出的气体之一就是水蒸汽。
