Thermal Ionization Plasma Generation and Spectrum Test

本文针对热电离等离子体如何生成问题进行研究。以火药燃气产生的等离子体为研究对象,通过分析火药燃烧过程的四个阶段和相应的气体生成物,讨论了火药燃气生成热电离等离子体的过程,并对能够生成热电离等离子体的分子数在气体总分子数中所占的百分比进行了计算。最后建立了一套热电离等离子体试验系统,采用光谱测试法对热电离等离子体进行测试,获得电子温度、电子密度等参数。该研究为热电离等离子体的进一步的应用提供了一定的理论依据。

This paper studies the generation of thermal ionization plasma. Taking the plasma produced by gunpowder gas as the research object, through the analysis of the four stages of gunpowder combustion process and the corresponding gas products, this paper discusses the process of gunpowder gas generating thermal ionization plasma, and calculates the percentage of the number of molecules to be able to generate thermal ionization plasma in the total number of molecules in the gas. Finally a set of thermal ionization plasma test system is established, and the method of spectrum test is used to test the thermal ionization plasma to get parameters such as electron temperature, electron density. This study provides certain theoretical basis for the further application of thermal ionization plasma.
