摘要：

The structure of n-fold rings in vitreous SiO2 is investigated using molecular-dynamics configurations. A recently developed interaction potential for SiO2 consisting of long-range Coulomb interactions, the effect of electronic polarizability, and three-body covalent forces is used in the molecular-dynamics study of the vitreous state. Results for the statistics of rings and distribution of interatomic distances and bond angles in the rings are presented for the vitreous state. The statistics of rings for the molten state is also discussed.
