摘要: The results covered in this paper provide breakdown data represented by Paschen curves for methanol, isopropanol and n-butanol, along with the corresponding axial profiles of emission Townsend regime discharge including optical spectra. were recorded range pd (pressure x electrode gap) from 0.10 to 3.00 Torr cm. spectra (OES) are wavelength 300 900 nm, discharges all studied alcohols. enabled identification species that participate these discharges. All three alcohols exhibit excited radicals OH (at 306.4 nm), CH 431.2 nm) Hα 656.4 produced mostly dissociative excitation electrons. Recorded us identify conditions where processes induced heavy particles (ions fast neutrals) dominant inducing discharge.
