射频等离子体探针诊断及尘埃晶格观测虚拟仿真实验设计

Design of Virtual Experiment on Probe Diagnostic of Radio-Frequency Plasma and Observation of Dust Lattice

针对射频等离子体探针诊断及尘埃晶格观测真实实验中激光和射频辐射的潜在危险大、设备成本高、仪器精密易损等实际教学问题,将虚拟仿真技术、前沿科研成果深度融入本科教学当中,建设了射频等离子体探针诊断及尘埃晶格观测虚拟仿真实验,目的是引导学生开展研究性、探索性学习,拓展应用物理专业实验教学内容的广度和深度。实践教学效果表明,坚持循序渐进、步步提高的“理论-实践-探讨-再实践”的实践教学方法,不仅可以拉近国家重大战略需求和科学前沿与本科生所学基础理论知识的距离,还可以增强学生的爱国精神,激发学生奉献祖国科研事业的决心和信心。

For the practical teaching problems of laser and RF radiation,high cost and precision of equipment in real experiments,a virtual experiment of probe diagnostic of radio-frequency plasma and observation of dust lattice is designed,which is deeply integrated with virtual simulation technology and scientific research achievements in the undergraduate teaching.The purpose of the experimental project is to guide students to carry out research and exploratory learning,and expanding the breadth and depth of experimental teaching content in applied physics majors.The practical teaching effect shows that the step by step improvement practical teaching method of“theory-practice-discussion-repractice”can shorten the distance between the major national strategic needs and the scientific frontier with the basic theoretical knowledge learned by undergraduates,can also enhance students’patriotic spirit,stimulate students’determination and confidence to contribute to the scientific research of our motherland.
