电子显微镜对真空度要求较高,从开机到正常工作需要的时间较长,一般在四十分钟以上能抽好高真空,如果要达到较好的稳定性,需要的时间更长。这对观察人员来说很不方便,影响观察时间,为克服这一缺点,我们将计算器的定时功能用于电镜,试验成功一种自动提前开机的办法,使观察人员一上班就能正常使用仪器,这 Electron microscopy requires a higher degree of vacuum, from the boot to the normal work takes longer, generally more than 40 minutes to pump a good high vacuum, if you want to achieve better stability, the need for longer. This is very inconvenient for the observer, affecting the observation time. To overcome this shortcoming, we used the calculator’s timing function in electron microscopy to test a successful auto-power-on approach that would allow observers to work as soon as they went to work Instrument, this
