摘要：
We discuss a recently developed theoretical model for ionic transport in glass, which offers a simple explanation to two long lasting problems in the physics of glassy ionic conductors: the anomalous dependence of conductivity on the modifier content and the mixed alkali effect. The model is based on the experimental evidence that ions maintain their distinct local environments and leads to the formation of fluctuating structural pathways. The connectivity of these pathways determines the ion mobility in the glassy network.
