摘要
从一般意义上给出了非平衡电弧加热射流光谱学诊断方法和结果。表明非平衡亚声速电弧加热射流中心是ＬＴＥ的，沿径向形成一非平衡囊兜，囊兜的最深位置约在１／２射流半径处。
This paper presents generally the method of spectroscopic diagnosis on non-equilibrium arc heated jet and the diagnosed results.It Will be seen from results that the state is of LTE at the center of subson-ic argon arc heated jet.Therc is a non-equilibrium area, the shape of which is much like a bag concealed inside the jet along the radial direc-tion. The maximum departure from LTE is in a half of jet radius from the center.
