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.
当观察扩展光源时，目镜中所看到的亮度只跟孔径和放大率有关，它跟焦比并没有关系。
1·Adjust the shutter speed and aperture.
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。
2·As the firemen dug away at the aperture they had opened, they found that the corridor had become a 15-foot deep shaft.
消防员们继续扩大他们挖开的孔，最后他们找到了走廊，并在那里打开了一个大约十五英尺深的竖井。
3·It widened smoothly. Soon he'd made an aperture twenty-five centimeters across.
它顺利地变宽了，很快成了一个25公分的孔。
4·Additionally, the accessory cartilages connect each lateral crus to the piriform aperture.
此外，附件软骨还将外侧脚与梨状孔连在一起。
5·The eye of a nautilus mollusk. The lens-less pupil works rather like the aperture of a pinhole camera.
鹦鹉螺之眼。这种没有透镜结构的瞳孔更像是针孔相机的孔。
1·Usually at the back of the stone on drop a few drops of ink, such as ink one soon, namely that exist within the stone loose particles or aperture, stone material quality is bad.
通常在石材的背面滴上一小滴墨水，如墨水很快四处分散浸出，即表明石材内部颗粒松动或存在缝隙，石材质量不好；
2·The leak of aperture is the main reason which affects the shielding effect. Therefore, the structure design of electronic equipment will directly affect its shielding effect.
孔洞、缝隙的泄漏是影响屏蔽效果的主要原因，因此，电子设备结构设计的型式将直接影响屏蔽效能。
3·The structure design and calculation and application of the aperture restrictor with simple structure, easy assembly and reliable usage are introduced.
本文介绍了一种结构简单、安装方便、使用可靠的缝隙节流器的结构、设计计算及应用。
4·Then microstrip antennas can be regarded as aperture antennas.
因此微带天线也可以看做一种缝隙天线。
5·Computer keyboard keys aperture stains and dust to clean up, these seem to have to carefully place, often let our cleaning job not start.
电脑键盘的按键缝隙容易留下污渍和灰尘，这些清洁起来似乎不得不小心翼翼的地方，往往让我们的清洁工作无从下手。
1·A new technique which combines the general network formulation and the connection algorithm is proposed to deal with the complex aperture coupling problems.
本文利用广义网络法结合连接算法分析复杂孔缝耦合问题。
2·The aperture constitute the main reservoirs of Carboniferous space provided for the oil and gas reservoir sites.
这些孔缝构成了石炭系的主要储集空间，为油气的储集提供场所。
1·Set the lens aperture to the aperture value designated by the flash unit according to the ISO setting your camera.
按照您相机上闪光装置ISO设置，设置好镜头的光圈大小。
