摘要：

A self-consistent steady-state spatially averaged collisional-radiative model in which the rate coefficients involving electrons are calculated from the solution to the electron Boltzmann equation has been developed for describing an atmospheric pressure plasma in helium-nitrogen (He-N-2) mixtures. The influence of small nitrogen concentrations (typically less than 1%) on the discharge characteristics is studied and compared,vith available experimental data. It is Sound that nitrogen is highly dissociated and that the density of metastable helium atoms is considerably reduced by the presence of nitrogen, even at such low concentrations.
