【摘要】：一定压强下对液体进行冷却,若避免晶化,则冷却中液体不可避免地转变为典型非晶态固体——玻璃.这种现象称为玻璃转变,是一种普遍存在的自然现象,涉及多体相互关联体系中众多基础理论问题.近几十年以来,玻璃转变问题的探索过程中,弛豫存在的普适性、其机理/物理图像及其对液体和玻璃性能认知的影响等一直是争论的热点.在梳理β弛豫研究进展的同时,本文尝试对未来β弛豫研究方向进行展望.
[Abstract]:If the liquid is cooled at a certain pressure, if crystallization is avoided, the liquid in the cooling process will inevitably be transformed into a typical amorphous solid-glass. This phenomenon is called glass transition, which is a common natural phenomenon. In recent decades, in the process of exploring glass transition problems, relaxation exists in universality. The mechanism / physical images and their effects on the cognition of liquid and glass properties have always been a hot topic. While combing the research progress of 尾 -relaxation, this paper attempts to prospect the future research direction of 尾 -relaxation.
