Activation theory of the viscous current of strongly viscous liquids

The equation capable to describe temperature dependence of viscous current of glass forming fusions in the wide range including areas of vitrification and increased temperatures was obtained. The equation contains three parameters, one of them - a preexponential multiplier - is estimated by extrapolation of curve viscosity to the increased temperatures (by means of Lagrange's polynom), and the other two - energy of delocalization of atom and potential of particle jump - serve as subracing parameters. The energy of delocalization of atom defined at adjustment is in satisfactory consent with calculation for model of the delocalized atoms. The nature of a viscous current of glasses and their fusions is discussed.
