光圈

Rbs were then photographed in haunted locations suggesting that it was a form of energy associated with the paranormal.

RB光圈在常出现的地方被拍到暗示著光圈是一种不寻常的能量形式。

Gaetano skirted the light, carefully keeping the boat in the shadow; then, when they were opposite the fire, he steered to the centre of the circle, singing a fishing song, of which his companions sung the chorus.

盖太诺沿着光圈的边缘航行，小心地使船保持在光线之外；就这样，当他们驶到火光正面的时候，他就笔直地驶入光圈的中心，嘴里唱起了一首渔歌，他的伙计们也同声合唱着。

Each F-number is known as a "F-stop".

每个光圈值称为一个"光圈档"。

F f-Number: A symbol that expresses the relative aperture of a lens.

f-制光圈∶一个表示镜头的相对光圈的单位。

The relation of the surface shape error to f-number and relevant spherical radius was achieved according to the reducing analysis model ignoring the local f-number. Two kinds of rhombic prism model are established by ZEMAX. According to the simulation results from ZEMAX, the correctness and limitation of the former methods are proved and analyzed. The results are used to analyze the effect of the surface shape error of the rhombic prism on parallelism of the emergent beam. The assignation plan of the surface shape error for each working surface is presented.

根据忽略局部光圈数的简化分析模型，获得面形误差对应光圈数与相关球面半径的关系，通过几何处理方法，求得一定面形误差对应的球面半径与平面倾角的关系，将斜方棱镜的工作面倾斜一定角度，运用折射定理，将具体面形误差转化为相应平面的倾斜角度，得到出射光相对于理想光轴的倾斜角度及其关系式，并在ZEMAX中建立斜方棱镜的两种模型。

Meter the scene, select an f-stop, set the autoflash aperture to the same f-stop, and shoot.

根据场景选择合适的光圈，将闪光灯的光圈设置为同样大小。

Stop Down: To decrease the diameter of the light-admitting orifice of a lens by adjustment of an iris diaphragm.

缩小光圈：镜头的焦距和光圈的有效直径之间的关系。一可调节的彩虹光阑，减少透镜光孔的直径。

This paper is the discussing about the aperture -coefficients of the Zoom Lens, the formula for the calculating is: F=f/d where.

该论文是探讨变焦镜头的光圈系数，镜头的光圈系数的计算公式：F=f/D(其中：F为光圈系数，f 为镜头焦距，D为光圈开口直径)。

Typical for many ultra-large aperture lenses you can experience some purple fringing in extreme contrast conditions at wide-open aperture.

对于大光圈镜头来说，你可以体验在光圈全开极端对比的情况下产生的紫边现象。

This works with slide film and digital.

在使用没有自动输出控制的闪光灯时，将闪光灯的感光度设为胶卷的二倍，对主体测光，机身选光圈整档，闪光灯设同样光圈。

It is also known as one of the most poisonous naturally occurring substances.

它也被称为一个最自然发生的有毒物质。

The greatest stress is found at the location on the cross section where V is the largest.

最大应力出现在横截面上V为最大的地方。
