The DNLR Approach and Relaxation Phenomena. Part I – Historical Account and DNLR Formalism

摘要: The relaxation phenomena defined by De Groot and Mazur (1962)describe the internal reorganizations linked to return toequilibrium of media subjected external perturbations lowamplitude (near equilibrium state). Far from equilibrium, anytheoretical approach these has include followinginformation: are multiple theirkinetics nonlinear. Indeed, much experimental evidence lead tothis conclusion. A classical example for analysis relaxationsnear glass transition is study volumerecovery PVAc (Polyvinylacetate) done Kovacs (1963).
