The authors examine the multivalued and oscillatory states in rich H/sub 2/-O/sub 2/-N/sub 2/ flames. It was shown that multiple stationary states in rich H/sub 2/-O/sub 2/-N/sub 2/ flames occur for a restricted closed region in the parameters. The equations for the monostationary boundary coincide with the equations for the boundary from the Routh-Hurwicz conditions. Oscillatory conditions can occur in the flame at small injection speeds. The approximate analytical study of the stationary states enables one to reproduce the actual picture if the results are edited in the light of the numerical experiments.
