Bifurcation transitions aremarked by vertical lines corresponding tojumps upward for n at T 0 =555K and downwardat T 0 = 490 K.At the initial parametric point:KE10+3= 1.176 ⋅107= 10000kl,KT⋅1/s,E−301= 5.53⋅10= 10000kl,K8cc⋅1/s,E20−3T8007006005004003300320 360 400 440 480 5205Fig. 2. Bifurcation diagram under nonisothermal conditional. Line 2 corresponds tointermediate stable state, lines 4 and 5, tounstable states (1) and (3) are the kinetic anddiffusion regimes, respectively.= 4736 ⋅1/s,E= 0, K= 20000kl,β = 20⋅1/s2+30214= 7.055⋅105T 0⋅1/s,the system under isothermal conditions at T 0 =500K has three stationary pointssaddle and two stable (nodes),one of which diffusion unstable. Proceeding from thisparametric point and varying the α and T 0 parameters had been found all thestationary states. The ones shown on bifurcation diagrams (Fig.1 and Fig. 2).The instability of uniform stationary states with respect to local perturbationsresults in the appearance of no uniform structures because of the development ofrandom perturbations.1,2T,n,c1,00,80,60,4nT/1000The Fig.3 shows domain structureat α=0.1 and T 0 =500K,D n =10 –3 cm 2 /s, D n* =10 –2 cm 2 /s,D cnn =0.1cm 2 /s, λ/c v ρ=0.2 cm 2 /s.0,20,0c0,0 0,2 0,4 0,6 0,8 1,0Referencesx/L[1].
