摘要：

A model of ionic conduction in glasses is developed, in which the transport of classical particles takes place by hopping between negatively charged sites with possible multiple occupancy. This relates the ionic conductivity of (1 - x)B2O3 + xLi(2)O with the structural changes in the glass due to the addition of the alkali metal oxide, which give the nature of the negative traps as a function of x. A mean field calculation based on these ideas correctly predicts the behaviour of the activation energy and explains the surprisingly simple Arrhenius behaviour of the conductivity.
