摘要：

X-射线衍射是表征材料结构的一类重要技术，在材料化学教学中具有举足轻重的地位。随着新型材料的不断发现，相应的先进X-射线衍射技术也应运而生。本文基于当前材料化学学科前沿，对高压同步辐射X-射线衍射技术、微焦斑X-射线衍射技术和同步辐射X-射线对分布函数三种先进技术进行介绍，旨在加深学生理解X-射线衍射相关基础知识的同时，能够拓宽科研视野，并提高解决问题的能力。

Abstract:

X-ray diffraction is a pivotal technique for material structure analysis, playing a fundamental role in materials chemistry. In light of the continuous discovery of novel materials, advanced X-ray diffraction methods have emerged at the forefront of materials chemistry. This paper introduces a teaching reform incorporating three advanced X-ray techniques into materials chemistry instruction: high-pressure synchrotron X-ray diffraction, micro-focus X-ray diffraction, and X-ray pair distribution function analysis. We anticipate that such a teaching reform will empower students to deepen their grasp of X-ray diffraction techniques, broaden their academic horizons, and refine their problem-solving skills.

Key words: X-ray diffraction, High-pressure, Micro-focus, Pair distribution function
