摘要：

The entropy of a glass-liquid quasiphase transition that depends weakly on the nature of vitreous systems is introduced in analogy with the Clausius-Clapeyron equation. We suggest a common nature for the elementary act of the softening process for glasses with different chemical compositions. The elementary act in question is reduced mainly to the ultimate strain (excitation) of an interatomic bond corresponding to the maximum attraction force between atoms.
