چکیده انگلیسی
Some examples of recent advances in experiment and theory that have impact on solution of the glass transition problem are briefly discussed. The fundamental importance of a special class of secondary relaxations called the Johari–Goldstein β-relaxations becomes clear from the recent advances. The main part of the paper addresses a recent research problem, which is the purported anomalous temperature dependence of the relaxation time of another secondary (γ) relaxation found by fitting dielectric relaxation data in several glass-formers. We show the anomalous T-dependence of this faster γ-relaxation is caused by the influence exerted by the slower Johari–Goldstein β-relaxation in the vicinity.
