aperture stop

基本解释

The results show that the dynamic spatial resolution in time direction has been improved by 15-20% when the aperture stop width is properly enlarged.
分析结果证明，在适当扩大孔径光栏宽度后，在时间方向上的动态空间分辨率可提高15～20％。
The system includes, in order from an object, a first lens group G1 having positive refractive power, an aperture stop S, and a second lens group G2.
按从物体起的顺序，该系统包括具有正折射光焦度的第一透镜组（G1）、孔径光阑（S）以及第二透镜组。

Ideally keep your f-stop constant in this process and as you have it on a tripod you can afford to close down your f-stop/aperture to give you maximum depth of field throughout your image.
保持光圈值不变，而且在三脚架上你能够用尽量小的光圈得到尽量大的景深。
