One important detail is that when the microscope is running and electrons are being accelerated to relativistic speeds, vacuum pumps are used to remove all the atmospheric molecules, thus creating a vacuum, similar to the vacuum of outer space.
一个重要的细节是, 当显微镜运时, 电子被加速到相对
速度,真空泵会去除所有的大气分子,从而形成真空, 类似于外太空的真空。
