Structural recovery of quenched and annealed glasses

摘要

A continuous approach to the multiordering parameter equations for glass transition phenomena is presented which leads to the unification of two successful phenomenological models. The nature of distribution functions, the temperature‐structural dependence of relaxation times, the experimental rate and the state of nonequilibrium during quenching, annealing, and heating are the essential parameters. The effect of distribution function of relaxation times on the enthalpy and heat capacity of glasses, and the sensitivity and convergence of the numerical calculation, are discussed. The theoretical calculation is then compared with the calorimetric measurements of polystyrene.
