Abstract
The influence of spatial inhomogeneity and temporal fluctuations of the parameters of equilibrium plasma on the intensity and shape of the lines in the spectrum of its radiation was investigated. A closed mathematical model based on the solution of the radiation transfer equation, which describes the formation of the emission spectrum of the plasma volume with given characteristics, has been constructed. A semianalytical approximation that permits adequate description of the line radiation spectra of optically transparent plasma has been developed. The laws of formation of the line radiation spectra of inhomogeneous fluctuating plasma volumes and the relations relating the characteristics of these spectra to the emissivity and local parameters of the plasma have been found. For the presentation of the results, we have chosen atmospheric‐pressure argon plasma.
