摘要
运用极限动力学模型和Adam-Gibbs理论,由β的温度关系容易得出玻璃化液体的VFI方程.根据关联区域内构型熵S_c的概念及其与弛豫时间的基本关系式,可得出伸展因子与构型熵的关系式;描述了液-玻相变温区构型熵的温度变化规律及其与等压热容的关系.
The VFT equation of supercooled liquids can be easily obtained according to the temperature dependence of β by using the extremal dynamic model and the Adam - Gibbs theory. The relationship between structural relaxation and configurational entropy is deduced from the expression of configurational entropy and the interacted Debye equation. Finally, the temperature relation of configurational entropy and isobaric capacity are described in the glass - liquid transition region.
