摘要

采用发射光谱法，研究了水电极介质阻挡放电中具有相同对称性的3种不同结构的六边形斑图演化过程的光谱特性。实验结果表明，随着外加电压的增加，放电首先形成六边形点阵斑图，然后是空心六边形斑图，最后是蜂窝六边形斑图。利用氩原子696.5 nm（2P

）谱线的展宽、氩原子763.2 nm（2P

）与772.1 nm（2P

）两条谱线强度比法和氮分子第二正带系（C

）的发射谱线，研究上述3种斑图的电子密度、电子激发温度及分子振动温度。结果发现，随着外加电压的升高，六边形点阵斑图、空心六边形斑图和蜂窝六边形斑图的电子密度逐渐减小，而电子激发温度和分子振动温度逐渐增加。等离子体状态的改变直接影响着斑图的自组织。

Abstract

The spectral characteristics of different kinds of hexagon pattern with the same symmetry in evolutionary process were studied in dielectric barrier discharge by optical emission spectrum. It is found that the discharge undergoes hexagon superlattice pattern

hollow hexagon pattern and honeycomb pattern with the increasing of the applied voltage. The electronic density

electron excitation temperature and molecular vibration temperature of the three kinds of patterns were investigated by the broadening of spectral line 696.5 nm

the relative intensity ratio method of spectral lines of Ar Ⅰ 763.2 nm (2P

) and Ar Ⅰ 772.1 nm (2P

) and the emission spectra of nitrogen band of second positive system (C

)

respectively. The results show that the electronic density of the hexagon superlattice pattern

hollow hexagon pattern and honeycomb pattern gradually decreases

while the electron excitation temperature and molecular vibration temperature of the three kinds of patterns gradually increase with the applied voltage increasing. It is found that the change of the plasma state has effect on the self-organization of the pattern.
