电镜工作时要求循环冷却水同时工作，并且在关闭电镜后冷却水还要继续循环１０—２０ｍｉｎ，以便使高真空扩散泵充分冷却，防止硅油蒸发污染镜筒。传统做法是在关闭电镜后，再等２０ｍｉｎ手动关闭循环冷却水，不但操作麻烦，降低了电镜的有效使用时间，还会因疏忽忘记关...
Electron microscopy work requires circulating cooling water at the same time, and after the closure of the electron microscope cooling water but also continue to cycle 10-20min, in order to make the high vacuum diffusion pump fully cooled, to prevent evaporation of silicone oil pollution tube. The traditional approach is to turn off the electron microscope, and then wait for 20min to manually shut down the circulating cooling water, not only the operation is cumbersome, reducing the effective use of electron microscopy time, but also because of negligence forget ...
