摘要：

The vibrational properties of models of vitreous silica constructed by molecular-dynamics simulation with different interatomic potentials have been investigated. The static and dynamical structure factors of the model systems are in good agreement with experimental data. Partial and total vibrational densities of states are presented. The characteristics of vibrational modes in different frequency ranges are investigated using a mode-projection technique.
