Oh, that's what you get for betting the chalk.

赌倍率最高马总是赔很惨嘛。

They caught that keeping Tom red-handed had a high-powered house open binoculars by his window.

们发现，为了让汤姆保持警惕，窗户旁边有一架高倍率双筒望远镜。

The issue with photography at high magnification is that there is inherently a very shallow depth of field.

高倍率摄影问题是天生具有非常浅景深。

You get maximum magnification when the real image is just barely inside the focal length of the eyepiece. .

当真实图像刚好在目镜焦距内时，您将获得最大放大倍率。

So, the magnifying power of optical tools is limited, because light acts like the wave that it is.

因此，光学工具放大倍率是 有限，因为光作用就像它波一样。

We start our investigations at a very small magnification, which is equivalent to the highest magnification, which you can actually reach with a light microscope.

我们从一个很小放大倍率开始我们研究，这相当于你用光学显微镜能达到最高放大倍率。

This magnification depends on the strength of the magnetic fields, the position of the lenses, and the position of the detectors and cameras.

此放大倍率取决于磁场强度、镜头位置以及探测器和相机位置。

While other scopes at the time were lucky to get 50-times magnification, Van Leeuwenhoek's had up to 270-times magnifying power, identifying things as small as one thousandth of a millimeter.

虽然当时其镜幸运地获得了 50 倍放大倍率，但范·列文虎克镜具有高达 270 倍放大倍率，可以识别小至千分之一毫米物体。

In order to find the magnifying power of the lens, you just divide the angle subtended by the virtual image by the angle subtended by your unaided eye.

为了求出镜片放大倍率 ，只需用虚 像对角除以肉眼对角。

After all of the like terms cancel out, you're left with a magnification equation in terms of the focal lengths of the objective lens and the eyepiece. .

在所有类似项抵消之后，就物镜和目镜焦距而言，您会得到 一个放大倍率方程。

The tiny meta-surface lens building blocks, about six hundred nanometers in length, can achieve the same resolution and magnification as a lens that is 5-6 centimeters in length.

微小超表面透镜构建块，长约 600 纳米，可以达到与 5-6 厘米长透镜相同分辨率和放大倍率。

Now, if you want to calculate the magnifying power of the telescope, just start with the same equation you used for the magnifying lens, but with a negative sign, because the image is flipped.

现在，如果你想计算望远镜放大倍率，只需从用于放大镜相同方程开始， 但要加上一个负号， 因为图像是翻转。

For example, a photographer who wants to buy a telephoto lens may confront a choice between two lenses that produce images of equal quality and with the same magnification, but one of which admits twice as much light as the other.

例如，想要购买长焦镜头摄影师可能会面临在两个镜头之间进行选择，这两个镜头可以产生相同质量和相同放大倍率图像，但其中一个透光量是另一个两倍。
