这是对玻璃形成熔体弛豫动力学的现有知识的回顾。弛豫过程的动力学对于玻璃的性能至关重要。讨论了描述玻璃结构弛豫的多种方法。目的是预测弛豫函数的形式以及结构弛豫 tau(r) 特征时间的温度依赖性。通过跟踪玻璃化转变温度 T-g 对加热速率的依赖性和 T-f 对冷却速率的依赖性，可以获得有关玻璃弛豫行为的重要信息。
This is a review of current knowledge on the kinetics of relaxation of glass-forming melts. The kinetics of the relaxation process is of prime importance for the properties of glasses. A number of approaches describing the structural relaxation of glasses are discussed. The aim is to predict the form of the relaxation function and the temperature dependence of the characteristic time for structural relaxation tau(r).Important information on the relaxation behaviour of glasses can be obtained by following the dependence of the glass transition temperature T-g on the heating rate and the dependence of T-f on the cooling rate.
