Title: Processes of chemoionization in the course of inflammation of a methane-oxygen mixture by a high-current gliding surface discharge in a closed chamber

Results are presented from experiments on the inflammation of a stoichiometric methane-oxygen mixture by a high-current multielectrode spark-gap in a closed cylindrical chamber. It is shown that, in both the preflame and well-developed flame stages, the gas medium is characterized by a high degree of ionization (n{sub e} ≈ 10{sup 12} cm{sup −3}) due to chemoionization processes and a high electron-neutral collision frequency (ν{sub e0} ≈ 10{sup 12} s{sup −1})
