摘要：
The random-walk model of structural dynamics is used to account for long-range cooperative phenomena in supercooled liquids. Coupling of structural units within ordered regions is shown, to cause narrowing of the distribution function for the energies of structural units: This approach allows to explain the Kauzmann paradox and to fit non-Debay susceptibility spectra obtained on so-called fragile glasses. The results are in quantitative agreement with existing experimental data.
