四十年前，Jonscher的开创性综述[Nature（伦敦）267，673（1977）NATUAS 0028 -083610.1038/267673 a0]揭示了导电材料的介电响应的特征在于“显著的普遍性”。证明了同样的响应模式也表现出剪切流变谱的非聚合物粘性液体，目前的贡献连接两个分支的凝聚态物理学：电荷传输的概念可以用于描述的质量流，反之亦然。基于这两种动力学的虚拟等效性，建立了液体的微观和宏观粘弹性特性之间的联系，类似于导电性的Barton-Nakajima-Namikawa关系。
Four decades ago a seminal review by Jonscher [Nature (London) 267, 673 (1977)NATUAS0028-083610.1038/267673a0] revealed that the dielectric response of conducting materials is characterized by a “remarkable universality”. Demonstrating that the same response pattern is exhibited also by shear rheological spectra of nonpolymeric viscous liquids, the present contribution connects two branches of condensed matter physics: Concepts developed for charge transport can be employed for the description of mass flow and vice versa. Based on the virtual equivalence of the two dynamics a connection is established between microscopic and macroscopic viscoelastic characteristics of liquids, resembling the Barton-Nakajima-Namikawa relation for conductivity.
