| contents | The twice-activation method for analysis of experimental viscosity-temperature data reveals a set of interconnected parameters describing the state of the flowing glass-forming liquid in terms of convergation point which describes an infinite set of viscosity-temperature relations for the liquid considered. The observed uncertainty in the viscosity-temperature behavior permits to consider glass-forming liquid as the self-organizing system realizing by the bonds wave as dissipative pattern. The acoustic bond wave and the switching bond wave are considered generally and in different groups of glass-formers: inorganic, organic and polymers. The demonstrated correlation between two coordinates of convergation point and kinetic and thermodynamic measures of fragility permits to resolve the problem of the measures discrepancy. |
