Abstract:	We use the reductive perturbation method to discuss the phase transition of the nonequilibrium superconductors induced by the injection of quasiparticles in the vicinity of the instability point N*p- N,. We solve the third order equation which is analogous to the time dependent Ginzburg-Landau equation exacily. We also discuss the behavior of various modes in the non-linear region for different N1 and temperature ranges. When the quasiparticle-phonon reaction is small, 9bN,>Nj>N,, we found that modes with wave number I9-9,,, 1 <k. and N:,<N, or modes with wave number j9-9,,, 1 >ko are damped, stable or unstable according to whether the initial disturbance So are less, equal to or greater than the critical disturbance S,.
