从光栅衍射到现代纳米晶体观测技术

UNDERSTAND THE NANOMETER OBSERVATION TECHNOLOGY BY BASIC OPTICAL KNOWLEDGE OF GRATING DIFFRACTION

本文从工科大学生现有的光学物理基础知识出发,拓展了大学物理教学内容,逐渐深入介绍现代科研纳米观测技术、X射线衍射以及电子衍射。以开阔大学物理教师的视野为目的,为大学物理教师更好地理解电子衍射和X射线衍射提供帮助,利于教师在工科大学生现有物理基础上讲解现代科研技术,把前沿科学引入教学,把最新科技知识传授给学生,也可以实现教学与科研相长,培养学生的科学素养,以此让学生认识到基础物理学习的重要性,认识到大学物理是前沿科学研究和工程技术的基础,从而提高学生学习大学物理的兴趣。

Based on the basic knowledge of optical physics obtained by engineering college students,the nanometer observation technology X ray diffraction and electron diffraction were gradually introduced in our paper to expand the content of university physics.Introducing the nanometer observation technology will broad the view of university teachers and help them to understand the modern scientific research technology X ray diffraction and electron diffraction.It is beneficial for teachers to introduce the frontier science into teaching and impart the latest science and technology knowledge to the engineering students based on their current physics basis,which can cultivate students＇scientific literacy and make them realize importance of learning basic physics.Help students to understand that the college physics is the foundation of frontier research and engineering technology,so as to improve students＇interest in studying college physics.
