Characteristics of the N2/O2 mixtures

The characteristics of the prebreakdown phenomena in low-pressure N
₂
/O
₂
mixtures under quasi-dc uniform field gap were investigated. The appearance characteristics expressed schematically. The light, voltage and current waveforms of prebreakdown phenomena and the onset voltage of glow discharges were measured under conditions of 1/spl les/ pd/spl les/ 6 (Torr.cm) for N
₂
/O
₂
mixtures. From these results it became clear that the forms of prebreakdown phenomena of the glow discharges observed under lowpressure N
₂
/O
₂
mixtures were divided into four types, and these appearance characteristics were expressed schematically and discussed.
