The Radiation of Semi-Bounded Plasma with Dielectric Film

The thermal radiation spectra of semi-bounded non-isothermal plasma separated by the homogeneous layer from the external transparent medium has been obtained. The results are written in the form of Kirchoff's law generalization when the thermal fields of external medium and different temperatures of radiation media are taken into account. It is noted the dominant contribution of the proper thermal radiation of the external medium into the one-sided energy density radiation flux. (author). 36 refs., 6 figs
