Abstract

Abstract We present a comparative analysis of dielectric spectroscopy and optical Kerr effect measurements of relaxation processes in glass-forming phenyl glycidyl ether. In particular we focus our attention on the structural α-relaxation process and the most important finding is the existence of a constant scaling factor between the characteristic times obtained by the two experiments in the high-temperature region.

玻璃形成液体的结构弛豫过程:光学克尔效应与介电光谱的比较
摘要本文对形成玻璃的苯缩水甘油醚弛豫过程的介电光谱和光学克尔效应测量进行了比较分析。我们特别关注了结构α-弛豫过程,最重要的发现是两个实验在高温区域得到的特征时间之间存在一个恒定的比例因子。
