摘要
For multicomponent sheet and lead glass, the delocalization energy of Delta epsilon (e) atoms is calculated from the experimental data on viscosity. It is shown that the value of Delta epsilon (e) remains constant in sufficiently broad temperature range in the glass transition region. The results are in good agreement with the calculation on the formula of the model of delocalized atoms, which includes the glass transition temperature and fraction of fluctuating volume frozen at this temperature.
