摘要: 简介了结构松弛的主要特点及其唯象Tool-Narayanaswamy-Moynihan(TNM)模型的建立,并用此模型对无机玻璃(Li2O·2SiO2)在不同老化时间及不同老化温度下的结构松弛行为进行了模拟.得到了4个可调参数X、β、△h*和A,其中β、△h*和A不随老化温度及老化时间而发生变化,X则随老化时间的增加而增大,随老化温度的降低而降低.

Abstract: The main characteristics of structural relaxation and the associated Tool Narayanaswamy-Moynihan(TNM) model are thoroughly introduced. The structural relaxation of an inorganic glass (Li2O·2SiO2) at different aging temperatures and aging times is found to be well modeled by the TNM model.

Key words: Inorganic glass(Li2O·2SiO2), Structural relaxation, Tool-Narayanaswamy-Moynihan(TNM) model
