The ratio δB/δG between the couplings of a relaxational process to compression and shear, respectively, is calculated in the Eshelby picture of structural rearrangements within a surrounding elastic matrix, assuming a constant density of stable structures in distortion space. The result is compared to experimental data for the low-temperature tunneling states in glasses and to Prigogine-Defay data at the glass transition, both from the literature.
在考虑周围弹性基质中结构重排的埃舍尔比(Eshelby)图像时,计算松弛过程分别与压缩和剪切耦合的比 δB/δG,假设在变形空间中稳定结构的密度保持不变。将结果与文献中玻璃低温隧道态和玻璃化转变时普里戈金-德费(Prigogine-Defay)的数据进行了比较。
