During the day the lower limit is about 8 to 10 times the aperture.

白天时的下限是孔径的8到10倍。

This is the ratio of the focal length of the telescope to its aperture.

这是指望远镜的焦距与其孔径的比值。

It works by separating the mirror flip and aperture opening into two steps.

它将镜面翻转和光圈打开分为两个步骤。

This mode needs a lot of light, and you can't adjust the aperture yourself.

这种模式需要较充足的光线，并且你不能在拍摄的时候调整光圈。

For example, the maximum power on a 60mm telescope (2.4 "aperture) is 142x."

比如，孔径为60 mm(即2.4英寸孔径)的望远镜最大放大率为142x。

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。

The synthetic aperture radar technology will increase the radar \ 's capability.

合成孔径雷达技术将提高雷达能力。

As you move onto the more expensive zoom lenses, they maintain a constant aperture.

当你继续研究比较昂贵的变焦镜头时，你会发现它们有着恒定的光圈。

Taking control of the shutter and aperture isn't easy, but the rewards can be great.

同时控制快门和光圈并不简单，但却绝对值得。

As you increase the shutter speed, you'll need to widen the aperture and vice versa.

让你增加快门速度的时候，你可能需要扩大孔径，反之亦然。

The main lens is fixed in place; there is no auto-focus, auto-aperture, or other gubbins.

主要镜头是固定的，没有自动对焦和自动光圈以及其他小配件。

At any given magnification, the larger the aperture, the brighter and sharper the image will be.

对于任何放大率的望远镜，孔径越大，其成像亮度越高，成像边缘越锋利。

You also need to set the proper film speed and aperture. This will all depend on location of the storm.

你还需要根据风暴的位置远近设置好适度的快门速度和光圈值。

But the principle of focusing rays through an aperture onto a two-dimensional surface remains the same.

但其原理通过孔径聚焦光线在一个二维表面是保持不变的。

The larger the aperture, the more light it collects and the brighter and clearer the image will be.

孔径越大，它收集的光越多，成像的亮度和清晰度就越好。

The APG-79 AESA synthetic aperture radar (SAR) has a higher success rate than previous radar technologies.

同先前的雷达技术相比，APG - 79 AESA合成孔径雷达(SAR)具有更高的成功率。

The limiting magnitude is directly related to aperture, where larger apertures allow you to see fainter stars.

边缘亮度直接与孔径相关，孔径越大，就能看到越暗的星。
