发射光谱分析法的专题物理实验教学

本文中提出了以棱镜或光栅摄谱仪为基础实验，结合工科院校专业特点开设发射光谱分析法的专题物理实验的实验教学方法．以润滑油中磨耗金属的微量元素分析为例对专题物理实验过程中的关键环节作了比较详细的讨论．在工科院校中结合工程问题开设专题物理实验是对本科学生进行科学实验基本训练的有效手段．

SPECIALIZED PHYSICAL EXPERIMENT TEACHING ON THE EMISSION SPECTROGRAPHIC ANALYSIS

The teaching method of specialized physical experiments with the emis sion spectrographic analysis based on the prism or grating spectrograph is put forward in this article.Such experiments are adapted for the specialities of an engineer ing college.Taking for example the analysis of trace elements of wearing metals in the lubricating oil,the authors have discussed in detail the key process of the specialized physical experiments.It is concluded that the specialized physical experiments associated with engineering problems are effective means for promoting the practising abilities of engineering students.
