MODEL OF THE GLASS TRANSITION

摘要: This paper examines the three well‐known empiricisms that accompany glass transition of fragile glass‐forming liquids: unusual thermodynamic behavior supercooled liquids is usually called Kauzmann paradox, temperature dependence relaxation time as embodied in Vogel–Fulcher law, and time‐domain law known Kohlrausch–Williams–Watts function. Mutually consistent descriptions all phenomena are presented. The paradox can be explained by recognizing ground states both liquid crystal, also dominant excitations these two states, similar many ways. implies phases have thermodynamics at low T. results from assumption localized regions must excited above a certain threshold enthalpy before they relax; falls, this becomes less accessible apparent activation to affect increases. resulting model with Montroll–Schlesinger–Bendler description relaxation, which explains third empiricism.
