It was found that the state of medium similar to the known propane–oxygen flame could arise under these conditions. Such a flame could still exist after turning off the discharge. The results of a comparison of the relative intensities of the generating components of the plasma–chemical reactions and their volumetric distribution when the discharge was turned on and off and several electro-physical discharge characteristics are given. %8 2018-08-27
