| 摘 要： | 使用水电极介质阻挡放电装置,在氩气和空气混合气体放电中,利用光谱方法测量了氮分子(C3Πu)的振动温度及其随空气含量的变化关系.计算中采用的是氮分子第二正带系(C3Πu→B3Πg)的发射谱线,顺序带组有:△v=-1,△v=-2和△v=-3.结果表明:大气压介质阻挡放电中氮分子振动温度范围为1 938～2 720 K,振动温度随空气含量的增加几乎是线性增加的.该工作对研究介质阻挡放电中等离子体的动力学过程具有重要意义.

| Abstract: | Vibrational temperature of N2 (C 3IIu) molecules in dielectric barrier discharge (DBD) in argon/air at atmospheric pressure, in which the water electrodes were employed, was measured by using a method of spectrum diagnosis. Emission spectral lines of the N2 second positive band system(C 3IIu --> B 3IIg) and the sequences of vibrational bands with deltav = -1, deltav = -2 and deltav = -3 were used in the calculation. The experiment results show that the molecular vibrational temperature of N2 is in the range from 1 938 K to 2 720 K, and it increases almost linearly with increasing the air content in gas mixture. These results are of great importance to the study of plasma dynamics of DBD. |
