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

赌率最马总是赔很惨嘛。

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，窗户旁边有一率双筒望远镜。

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

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，您将获得最大放大率。

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

因此，光学工具放大率是 有限，因为光作用就像它波一样。

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.

虽然当瞄准镜幸运地获得了 50 放大率，但范·列文虎克瞄准镜具有达 270 放大率，可以识别小至千分之一毫米物体。

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率。

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.

为了求出镜片放大率 ，只需用虚 像对角除以肉眼对角。

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。
