摘　　要：透射电镜衍射是现代测试分析技术中极其重要的一环,然而倒易空间的抽象与烦琐的数学基础使得多年的教学效率显得并不理想,究其原因是因为电镜的昂贵导致课堂的教学与实际问题分析脱节,学生对其原理以及图像的处理方法的理解只是云里雾里、一知半解。本文对如何运用倒易空间理论分析TEM图像进行了深入的探究,旨在培养学生应用所学知识解决实际的工程问题。Transmission electron diffraction is a very important part of the modem test and analysis techniques. However, reciprocal space abstract and complicated mathematical foundation makes the teaching efficiency is not ideal for many years.The reason is that electron microscopy expensive lead to classroom teaching and practical problem analysis,students＇ understanding of the principle and process of image just fog,a little knowledge.In this paper, how to apply theory of reciprocal space analysis carried on the thorough study of TEM images,aims to cultivate students apply their knowledge to solve practical engineering problems.
