在2.5kPa-20 kPa气压范围内，对直流正电晕放电中提取的离子进行了质谱研究。证实了质谱的多组分特征。在质谱中观察到的主要系列的离子的类型[H3 O]+（H2O）n，特别是在低电流制度。在电晕放电的高电流状态或“流光”状态中，也发现了原子氮和氧离子，但与对应于分子离子的峰的强度相比，这些离子的强度相对较低。给出了[O2]+及其水合形式从质谱中消失的新机制。这是基于由三体过程起源的一组逐步过程。O2++H2O+M→O2+.H2O+M该模型还能够解释空气中存在水引发的其他一些现象，以及在干燥空气中观察到的影响。© 1997 John Wiley & Sons，Ltd.
A mass spectrometric study of ions extracted from DC positive corona discharges in ambient air has been carried out within the air pressure range of 2.5 kPa–20 kPa. The multicomponent character of the mass spectra was confirmed. The dominant series of ions observed in the mass spectra were of the type [H3O]+(H2O)n especially in the low current regime. In the high current regime, or ‘streamer’ regime of the corona discharge, atomic nitrogen and oxygen ions were also discovered, but the intensities of these were relatively low in comparison with the intensities of peaks correpsonding to the molecular ions. A new mechanism responsible for the disappearance of [O2]+ and its hydrated forms from the mass spectra is given. This is based on the set of stepwise processes originated by the three-body process. O2++H2O+M→O2+.H2O+M The model is also capable of explaining some other phenomena initiated by the presence of water in the air, as well as the effects observed in dry air. © 1997 John Wiley & Sons, Ltd.
