摘要
设计了一组基于大气压等离子体射流的专业实验教学项目,给出了项目的实施方案,并展示了教学实践结果。首先,介绍了实验目的、原理、实验装置设计和教学内容设置,并针对射流放电功率测量和聚合物表面改性开展实践教学。结果表明,该项目实验原理清晰,实验装置结构明了、操作灵活,实验内容容易开展和实现。该项目一方面能加深学生对等离子体基础知识的认识;另一方面也培养了学生继续探索研究的兴趣。
A set of professional experimental teaching projects based on atmospheric pressure plasma jet was designed. The implementation plan of the project was given and the results of teaching practice were presented. Firstly,the purpose,principle,experimental device design and teaching content setting are introduced,and practical teaching is carried out for jet discharge power measurement and polymer surface modification. The results show that the experimental principle of the project is clear,the structure of the experimental device is easy to understand,the operation is flexible,and the experimental content is easy to develop and implement. On the one hand,the project can deepen students’ understanding of the basic knowledge of plasma;on the other hand,it also cultivates students’ interest in continuing to explore and research.
