摘要：

采用横向磁场驱动的滑移弧等离子体发生器产生非平衡、大气压下的等离子体。用氮分子谱和OH基谱来估算滑移弧等离子体射流中的重粒子温度。从实验数据的比较来看，从氮分子谱获得的重粒子温度相对较低，而从OH基谱获得的重粒子温度与磁稳滑移弧放电的重粒子温度比较接近，大约在2400~ 2700 K的范围内。

关键词: 滑移弧, 重粒子温度, OH基

Abstract:

A generator of the gilding arc discharge, which is driven by the transverse magnetic field, is used to produce non-equilibrium plasma at atmospheric pressure. The spectra of N2 and OH radical are used to estimate the heavy particle temperature of the gliding arc plasma jet. Compared with the heavy particel temperature of the magnetically stabilized gliding arc discharge, the heavy particle temperature obtained from N2 spectrum is lower. Whereas, the heavy particle temperature obtained from OH radical spectrum is the same order as that of the magnetically stabilized gliding arc discharge, and is approximately in the range of 2400 K to 2700 K.

Key words: Gliding arc, Heavy particle temperature, OH radical
