The second is using a secondaryelectron detector that could function in this non vacuum sample environment.
二是使用了一个在样品室非真空环境下仍然能起作用的二次电子探头。

Based on the imaging principle of SEM, the equation for illustrating the theoretical resolution of secondaryelectron image has been deduced in this paper.
本文是从扫描电子显微镜的成像原理出发,推导了有关阐明二次电子像理论分辨率的公式。
