摘要：

The generalized thermodynamical scaling of the glass transition dynamics was investigated. A wide range of temperatures and specific volumes were shown through the use of the scaling parameter T-1Vδ. It was also observed that the scaling was able to accurately depicted the dynamics for van der Waals, associated liquids and for polymers. The result shows that the consequent modification of the usual fragility plot directly reveals the relative contributions to the super Arrhenius character from temperature and specific volume.
