摘要
通过对透射电子显微镜像差的简化分析,得到在透射电子显微过程中最佳离焦量的选择原理,并进一步讨论了消除像差影响的方法,给电子透射显微像的数字模拟提供了较简便的处理方法.
Based on the simplified analysis of the aberration of the transmission electronic microscope, the principle of selecting optimum defocus in the image is carried. Furthermore, the method of eliminating the aberration is discussed which is simply used in the digital simulation of transmission electronic microcopy.
