摘要：利用两个半球形水电极介质阻挡放电装置，在空气中实现了弥散放电，采用发射光谱法，对分子振动温度、分子转动温度及电子平均能量等随电压的变化进行了研究。实验利用氮分子第二正带系(C ³Π_u→B ³Π_g)的发射谱线得到了氮分子的振动温度;通过氮分子离子(N⁺₂)的第一负带系(B ²Σ⁺_u→X ²Σ⁺_g)的发射谱线计算了氮分子的转动温度;采集了氮分子离子391.4 nm和激发态的氮分子337.1 nm两条发射谱线的相对强度之比，研究了电子的平均能量的变化。结果表明：随外加电压的增加，分子的转动温度呈上升趋势,分子的振动温度呈下降趋势, 电子能量呈缓慢的下降趋势。

Abstract：The diffuse discharge plasma in air was observed in a dielectric barrier discharge with two semispherical water electrodes. The variations of vibration temperature, rotation temperature, and average electron energy as the function of the applied voltage were studied by emission spectroscopy. The vibration temperature and the rotation temperature were calculated through the second positive band system (Ｃ ^３Π_ｕ→Ｂ ^３Π_ｇ) of N⁺₂ and the first negative band system (Ｂ ²Σ^＋_ｕ→Ｘ ²Σ^＋_ｇ) of N⁺₂ respectively. The average electron energy was studied by intensity ratio of 391.4 and 337.1 nm. It was found that the rotation temperature increases with the applied voltage increasing, while the vibration temperature and the electron energy decrease.
