摘      要：A simplified method for calculating the spectral emission of nonequilibrium air plasmas is *** order to obtain the nonequilibrium energy level populations,the nonequilibrium coefficients are introduced into the Saha-Boltzmann *** nonequilibrium coefficients are calculated by using several significant radiative *** approach to the determination of nonequilibrium electronic energy level populations of diatomic molecules is also *** on the method,spectral emission of atoms and molecules in a typical air plasma cell is *** results reveal that there is a significant difference between the nonequilibrium and equilibrium *** apply the method to the nonequilibrium AVCO R-156 *** agreement with the NEQAIR code and the measured data is shown,indicating that the method is reasonable and has good accuracy.
