You get the same amount of light with a large aperture and a fast shutter speed as you do with a small aperture and a slow shutter speed.
你使用大光圈以及慢速快门所得到的光和你使用小光圈以及高速快门得到的光是一样多的。
Portrait mode chooses a large aperture (a small 'f' number) which will make the depth of field (the amount of your shot in focus) smaller.
人像模式用一个大光圈(f值小)，而让景深(清晰对焦的那部分)变小。
Since the amount of light reaching the camera is dependent on the aperture, the overall exposure is altered by changes in aperture.
由于光圈控制着进入相机的光线总量，也就是说曝光强弱可以由光圈来控制。
This is because you halved the amount of light being let through the aperture opening, but let in twice as much light by keeping the shutter open longer.
这是因为前一组你用了一半的光圈，而后一组用了一半的快门时间。
The porous materials were characteristic of developed void space structure and aperture increased with the increment of the template amount.
多孔氧化硅材料孔隙发达，孔径随模板剂用量的增加而增大；
In a physical lens system, the aperture is adjusted to limit the amount of light entering the system.
在物理镜头系统中，光圈调整光线进入系统的数量极限。
