4·While most conventional airborne radars rely on some form of mechanically scanned antenna to transmit and receive signals, active electronically scanned array (AESA) sensors employ a fixed aperture.
当多数常规机载雷达依靠机械扫描天线收发信号的时候，有源电子扫描阵列(AESA)传感器却使用固定的孔径。
5·When viewing extended objects, the apparent brightness seen in the eyepiece is a function only of aperture and magnification, it is not related to focal ratio.

校准快门速度和光圈。
2·Photograph it at different shutter speeds, from slow to fast (adjust your aperture to maintain correct exposure), and see what affect it has on the appearance of the subject in the photo.
尝试用不同快门速度拍摄，由低到高(调整光圈以获得正确曝光)，注意观察它为你的拍摄带来了何种影响。
3·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.
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。
4·If star trails are desired, using a large aperture and higher sensitivity (ISO 200-400) can enhance the brightness of each streak.
如果需要星光轨迹，那么使用大光圈和较高感光度(ISO 200 - 400)就能提高每条轨迹的亮度。
5·Night photography is subject to the same set of constraints as daylight photography - namely aperture, shutter speed and light sensitivity - although these are all often pushed to their extremes.
夜间摄影与白天摄影受到同样条件的约束——即光圈，快门速度，感光度——不过它对于这些参数的控制都要达到极致。
1·Most of the energy is lost through heat loss through the reactor's wall or through the re-radiation of sunlight back through the device's aperture.
而大多的能量都通过反应器壁的热耗散，或者通过装置开孔的太阳光再发散损失掉了。
