The phenomenon of wave-length increase occurred in Rayleigh-Bénard convectiou is analysed by numerical method, and the result obtained is in good agreement with experiment. The calculations for stability and entropy production show that the criterion of maximum entropy production for relative stability of steady states is correct.
