浅谈电子显微学新发展及相关课程的优化改革

On the New Development of Electron Microscopy and the Optimization Reform of Related Courses

随着新材料、新结构的设计出现,从原子分子尺度解析材料构效关系的需求使得具有高空间分辨分析能力的电子显微分析技术成为物理、材料科学、化学催化、微电子及医学生物等多学科的必要研究手段。近年来的球差技术、原位电子显微学、三维重构以及直接电子探测等新技术进一步拓展了电子显微学的研究及应用领域。基于新技术的发展,为提升学生在实际科研过程中对电子显微学技术的实践应用能力,针对相关课程的教学内容、教学方式及教学实践等,探讨教学改革及教学质量的提升思路。

with the emergence of new materials and new structures,the need to analyze the structure-activity relationship of materials from the atomic and molecular scale makes electron microscopic analysis technology with high spatial resolution analytical ability one of the necessary research means in physics,material science,chemical catalysis,microelectronics and medical biology.The new techniques,such as spherical aberration,in situ electron microscopy,three-dimensional reconstruction and direct electron detection,have further expanded the research and application fields of electron microscopy in recent years.Based on the development of new technology,in order to improve the students'practical application ability of electron microscopy technology in the actual scientific research process,this paper discusses the teaching reform and the promotion of teaching quality according to the teaching contents,teaching methods and teaching practice of the courses related to electron microscopy.
