- Аннотация: The methods of emission spectroscopy, shadow photography, and integral radiation of a discharge with time resolution are used to study the initial stages of the development of a microwave discharge in liquid hydrocarbons when argon is supplied to the discharge region. As a representative of a wide range of hydrocarbons, the petroleum solvent Nefras C2 80/120 is used. With the help of shadow photographs, the change in the structure of the discharge with time was studied, and the sizes and growth rates of the gas bubble with plasma are determined. The emission spectra of the discharge, obtained at an exposure time of 1 ms, shows that, in addition to the usual Swan and CH bands, the spectrum contains atomic emission lines of Hα and of a carbon ion. The presence of these lines is associated with the big role of electron impact in the kinetics of processes in plasma at short times.
