中文摘要：
在纯空气或者空气-氩气混合气体介质阻挡放电装置中,观察到由中心点、顶点和连线组成的亮暗点蜂窝斑图.3套结构呈现出了不同的亮暗状态,表明它们的等离子状态和参数可能不同.本工作利用发射光谱法,研究了其分子振动温度和转动温度随氩气体积分数的变化情况.结果表明：在同一条件下,分子振动温度由低到高依次为中心点、顶点、连线,而转动温度则几乎相同.随着氩气体积分数的增加,3套结构的分子振动温度都呈下降趋势,转动温度则变化不大.
英文摘要：
The bright and dark dot honeycomb pattern composed of center spot,vertex and spot of the line can be observed in a dielectric barrier discharge（DBD） device filled with air or its mixture with argon. The brightness of the three sets of structures is different. It indicates that the parameters and the states of the plasma may be different. The molecular vibrational temperatures and the rotational temperatures of the three sets of structures are measured by using optical emission spectra under different argon concentration. The results show that the sequence of the molecular vibrational temperatures from the highest to the low- est is the spot of the line, the vertex, the center spot. The rotational temperatures of them remain constant. The vibrational temperatures of the three sets of structures decrease with the rising of the argon concentra- tion while the rotational temperature changes little.
