摘要：

Dynamic mechanical relaxation measurements have been carried out in vitreous borates in the transition region at frequencies ranging from 2.5 to 10 s-1. The observed loss peaks are caused by network motions. Their temperature positions are related to the degree of cohesion of the systems. The temperature dependence of the relaxation times can be described by a free volume theory resulting in the WLF equation, as is verified in the case of B2O3. © 1978.
