摘要
Supercooled liquids — at temperatures below their normal freezing point — can undergo a subtle transition to a microscopically fixed, yet amorphous, state: a glass. The temperature of this transition depends on how quickly the liquid is cooled, so it seems more natural to describe the process in terms of kinetics, rather than some immutable thermodynamics. But it seems that the dynamic properties of glass-forming liquids can be related to an underlying energy landscape.
