本文研究了介质阻挡放电产生的非热大气等离子体中旋转温度与等离子体气体温度之间的关系。不同的参数进行了修改（如气体温度，分子分数）在氩气水气体混合物。用光谱法测定了OH（A）的转动温度。结果表明，在主要由原子物种，即稀有气体组成的混合物中，OH（A）转动温度与气体温度流光强烈相关。在混合（原子和分子）等离子体中，似乎旋转温度可以构成流光区域中重粒子平移能量的方法。
This study was dedicated to the correlation between the rotational temperature and the plasma gas temperature in a non-thermal atmospheric plasma obtained by a dielectric barrier discharge. Different parameters were modified (e.g. gas temperature, molecular fraction) in argon water gas mixtures. The rotational temperature of OH(A) was spectroscopically measured. It is shown that in mixtures mainly composed of atomic species, namely rare gases, the OH(A) rotational temperature is strongly correlated with a gas temperature streamer. In mixed (atomic and molecular) plasmas it seems that the rotational temperature can constitute an approach to the translational energy of heavy particles in the streamer areas.
