The setup and hold times, why are they even there? How can we find out how high they are? The logic gates are nowadays built most of the time, again, in so-called CMOS technology.

设置和保持时间，什么它们里？我们怎样才能知道它们有多高？如今，逻辑门大部分时间都是采用所谓的 CMOS 技术构建的。

The purpose of having two systems is that the phosphorescent screen and camera is used to ensure that the electron beam and magnetic lenses are set up properly, as an incorrectly focused beam could damage the sensitive CMOS camera.

采用两个系统的目的是利用磷光屏和相机来确保电子束和磁透镜设置正确，焦错误的光束可能会损坏灵敏的 CMOS 相机。

When you're ready to capture a high-resolution image, the phosphorescent screen moves out of the way, and the image is captured using the second system with a more sensitive CMOS camera that has a higher resolution and dynamic range.

当您准备捕捉高分辨率图像时，磷光屏会移开，并使用第二个系统捕捉图像， 该系统配备有更灵敏、分辨率和动态范围更高的 CMOS 相机。
