摘要：

The microscopic dynamics of two archetypal molecular glassy materials is discussed on the basis of comparisons between experimental and computer simulation results. Such an approach enables one to establish the microscopic origin of the high-frequency relaxations and the survival in the liquid phase of collective excitations characteristic of the glass. Finally the existence of a length scale involving the coupled motions of groups of particles is inferred from the analysis of several experimental and simulated quantities.
