提出了一种新的大气压氦气直流辉光放电。电流-电压行为和光谱特性强烈表明，该系统的工作在辉光区，尽管高压。扩散和极其稳定的放电通常在300 - 900伏的电压范围内（在电流控制模式下）和在几十到几百毫安的电流范围内操作。一些选定的物种的空间分辨光谱测量。旋转温度pro.使用OH发射光谱计算Ies，在正柱中产生范围从1300至1600 K的值。
A novel direct current glow discharge sustained in helium at atmospheric pressure has been developed. Current - voltage behavior and spectroscopic characteristics strongly suggest that the system operates in the glow regime, in spite of the high pressure. The diffuse and extremely stable discharge is typically operated within a voltage range of 300 - 900 volts ( in the current- controlled mode) and at currents ranging over tens to hundreds of milliamps. Spatially resolved spectroscopic measurements of some selected species are presented. Rotational temperature pro. les were calculated using the OH emission spectrum, yielding values in the positive column ranging from 1300 to 1600 K.
