光圈的大小用“f”来代表。
光圈的大小不仅影响感光程度，同时还影响在对焦范围的大小。
The size of the aperture not only affects how much light reaches the sensor, but also how much of the image is in focus.
现在你已经了解了这两个参数——快门速度和光圈大小，他们从本质上来说有同一个功能：控制进入相机的光线总量。
So you have these two parameters, shutter speed and aperture size, both of which do essentially the same thing: control how much light gets in.
那么现在，进入了第二部分的我们将要开始学习光圈大小以及快门速度，让我们这就开始吧。
Now in part two we're going straight to manual mode to learn about aperture sizes and shutter speeds. So let's do this thing.
每组数字并非是光圈打开大小的特定值，只是一个程度的相关体现。
Each number does not necessarily correspond to a specific size of the aperture opening, but is a relative number.
按照您相机上闪光装置ISO设置，设置好镜头的光圈大小。
Set the lens aperture to the aperture value designated by the flash unit according to the ISO setting your camera.
这种花纹的织法使纬丝编织更密集和较小的光圈大小，可以在不放弃布的厚度来实现。
This weave pattern enables the weft wires to be woven more densely, and much smaller aperture sizes can be achieved without forsaking cloth thickness.
光圈孔的大小，可从镜头的焦距与焦距比数中计算出来。
The aperture size (area of the aperture) of a lens could be calculated from focal length and the correspondent f-number.
针对视频监控中摄像机镜头光圈大小、图像聚焦、图像变焦三项参数的控制问题，介绍了一种基于89c51单片机的镜头控制电路的设计。
Abstract: The design of camera lens control circuit based on 89c51 is introduced. This circuit can adjust parameters of camera such as aperture, zoom and focusing.
波浪墙上，大大小小的光圈是落入水面的雨滴，生动而充满活力。
On the wave walls, big and small shining circles are dropping into the river like raindrops, full of vividity and vigor.
