摘　　要：设计了低气压气体放电等离子体综合实验平台,利用该平台可以开展气体直流击穿特性、气体放电伏安特性和等离子体基本参数静电探针诊断等系列实验项目的演示和教学。针对气体击穿特性实验平台的设计和实验方法,结合开展低气压气体直流击穿特性实验教学内容,介绍了平台的设计技巧、实验教学所需准备、课堂组织和实验技巧,分析了教学实施过程遇到的问题,提出了解决方案。教学实践表明,安全问题、气体击穿临界点的判定、首次测量气压点的选择、实验数据点的分布与拟合是课程顺利开展的关键因素。Based on the accumulated experiment experience on equipment development of Key Laboratory of Materials Modification by Laser, Ion and Electron Beams of Ministry of Education, the superior strength of National Key Disciplinary of Plasma Physics, we summarized the research achievements in gas discharge technology, designed and constructed a comprehensive gas discharge equipment platform. Three courses including DC discharge breakdown characteristics, V-I characteristics, electrostatic probe diagnostics were carried out using this platform. In this paper, the design idea and equipment module were recounted, the preparation, the class organization, the experiment skills were described. Moreover, the main problems during the courses and the corresponding solutions were also introduced.
