摘要：

A refined model is presented for the structure of silica glass. This modulated network model is a direct heir not only to the continuous random network model of Zachariasen, but also to the various micro-crystalline models. It consists of domains of six-ring networks linked by interfacial material containing rings of other sizes. The model is consistent with available diffraction data and is supported by some new geometrical theorems which lead to important restrictions on the network topology. © 1990 Elsevier Science Publishers B.V.
