Interface dynamics of glass state were discussed in this paper. A one-dimensional Edwards-Anderson model was used to simulate the kinetics of domain growth. Based on free volume theory, the non-Arrhenius relation was obtained: τ = τ0exp[E0/kB(T - Tf)]α, where α = df/d (dfbeing the fractal dimensionality of the system) reflected the stiffness of the domain wall in this non-equilibrium system. Detailed examination of the relaxation of Edwards-Anderson order parameter and local domain parameter at glass transition temperature showed that a short time relaxation period occurred before the system relaxed toward realistic equilibrium state. This phenomena was compared with the similar overshooting effect in Ising model at critical point and we concluded that these overshooting effects should contribute to the non-linear relaxation of domain far from equilibrium. The dynamic exponent of domain growth at Tfwas given.
