Analysing the transformation phenomena of glass, we emphasize that the fundamental irreversible change is caused by the network deformation. Further, we note that the rate equation of the network deformation plays the essential role in the stabilization process of glass and that this equation can be assumed in a simple form with the use of the network temperature which represents the state of network configuration. Next, we apply above equation to the analysis of the density data by Daragan and show that the activation energy of the rate mechanism is dependent upon the network temperature in accordance with the theory and its numerical value is nearly equal to the activation energy of viscosity.
