The electron swarm parameters in N_2,SF_6,and their mixtures are analyzed for reduced fields E/p_<20> ranged from 50 to 250 [Vcm^<-1>torr^<-1>]by a Boltzmann equation method presented by W. R. L. Thomas for a Steady State Townsend method. The swarm parameters estimated in this analysis are shown to be in close to the dispersive experimental values obtained by many precursors. This paper also shows the good result that the values of the limiting reduced fields analyzed by the estimated parameters are very close to those of the fields derived from the breakdown strength of the gas mixtures under the practical applied voltages. Consequently, the validity of the analysis for estimating the swarm parameters in predicting the limit-field values in the binary gas mixtures has been concluded.
