玻璃粘度与温度关系研究发展现状

Progress of Research of the Glass Viscosity-Temperature Relationship

本文综述了玻璃粘度与温度关系的描述方法,介绍了各个公式的优缺点。虽然John C.Mauroa,Yuanzheng Yue等人在提出的Mauro-Yue公式跟VFT公式、AG和AV公式一样都有三个参量,但是该公式克服了VFT公式和AV公式在低温下存在很大的系统误差的问题,而且对有机物和无机物液体的粘温关系都可以描述。

This paper reviewed the description methods of relationship between viscosity of glass and temperature,then introduced the advantages and disadvantages of each formual. Although the Mauro --Yue Formual which John C. Mauroa, Yuanzheng Yue proposed had the same number of three--parameters as VFT and AV formuals,it solved the singularity deviation of VFT and AV formual in low temperature,also described the viscosity temperature relationship for both inorganic and organic liquids
