高粘流理论
Theory of the highly viscous flow
摘要：
最近的理论治疗的固有状态之间的不可逆跳跃与剪切空间中的恒定密度扩展到一个完整的理论，归因于剪切松弛结构Eshelby重排涉及软模式的创建和湮灭。该方案解释了Kohlrausch指数接近1/2和连接到低温玻璃异常。导出了不可逆和可逆Kohlrausch弛豫时间分布之间的连续关系。全谱可以用在许多方面，不仅描述剪切松弛数据，而且还涉及剪切松弛数据介电和体积松弛谱，并预测从剪切松弛数据老化，证明了最近的老化实验。
英文摘要：
The recent theoretical treatment of irreversible jumps between inherent states with a constant density in shear space is extended to a full theory, attributing the shear relaxation to structural Eshelby rearrangements involving the creation and annihilation of soft modes. The scheme explains the Kohlrausch exponent close to 1/2 and the connection to the low temperature glass anomalies. A continuity relation between the irreversible and the reversible Kohlrausch relaxation time distribution is derived. The full spectrum can be used in many ways, not only to describe shear relaxation data, but also to relate shear relaxation data to dielectric and bulk relaxation spectra, and to predict aging from shear relaxation data, as demonstrated for a very recent aging experiment.
