本文描述了大气压非平衡等离子体的雾喷射光学发射光谱诊断。对于本研究中测试的条件，根据 Hβ (486 nm) 和 OH (309 nm) 光谱估计电子数密度和气体温度分别约为 1015 cm-3 和 440–540 K。 N2 和 OH 旋转温度的比较表明，OH 旋转光谱的双温度分析即使在喷射雾气的情况下也能提供气体温度。
This paper describes optical emission spectroscopic diagnostics of atmospheric-pressure non-equilibrium plasma with mist injection. Electron number densities and gas temperatures are estimated from Hβ (486 nm) and OH (309 nm) spectra to be on the order of 1015 cm-3 and 440–540 K, respectively, for the conditions tested in this study. Comparison of the rotational temperatures of N2 and OH indicates that two-temperature analysis of OH rotational spectra provides gas temperature even with mist injection.
