We also studied simple magnifiers and how to generate an enlarged virtual image.

我们还研究了简单的放大镜以及 如何生成放大的虚拟图像。

So that's a magnifier of the warming in the Arctic, and this has been predicted.

所以这是北极变暖的放大倍数，这已经被预测到了。

Paul lifted the seal on the pack, pulled out a tiny micromanual with glowtab and magnifier.

保罗揭开包装上的封条，拿出一本带有发光标签和放大镜的微型微型手册。

He pressed the shallower one and the book spread open on his palm, its magnifier sliding into place.

他按了按较浅的那本书，书在他的手掌上张开，放大镜滑入原位。

Any simple magnifier consists of a single converging lens, which produces a virtual image that enlarges an object.

任何简单的放大镜都由一个 会聚透镜组成，它会 产生放大物体的虚像。

This equation, which holds true for all magnifiers, tells you that this particular lens has a magnifying power of three.

这个等式适用于所有放大镜，它 告诉你这个特殊的镜头有 3 倍的 放大率。

This image is very small, but the eyepiece acts as a magnifier, forming a large, virtual image for the observer to view.

这个图像非常小，但目镜 起到放大镜的作用，形成一个大的虚拟 图像，供观察者观看。

If you had, say, a small leaf that you wanted to inspect, you’d just put the leaf inside the focal point of the magnifier.

如果你有，比如说，你想检查一片小叶子，你只需将叶子放在放大镜的焦点内。

If you had, say, a small leaf that you wanted to inspect, you'd just put the leaf inside the focal point of the magnifier.

如果你有，比如说，你想检查一片小叶子 ，你只需把叶子放在 放大镜的焦点内。

A simple magnifier isn’t enough to study objects on the cellular scale, so we’ve developed compound microscopes, which like a telescope, use objective lenses and eyepieces to magnify objects.

一个简单的放大镜不足以在细胞尺度上研究物体，因此我们开发了复合显微镜， 它像望远镜一样， 使用物镜和目镜来放大物体。
