cze	Strukturální relaxace amorfního Ge38S62 studovaná pomocí dilatometrie a kalorimetrie	The structural relaxation of Ge38S62 glass has been studied by length dilatometry and calorimetry. The Tool-Narayanaswamy-Moynihan model was applied on obtained data of structural relaxation and parameters of this model were determined: Dh*=483?2 kJ/mol, ln(A/s)=-81?1, b=0.7?0.1 and x=0.6?0.1. Both dilatometric and calorimetric relaxation data were compared on the basis of the fictive relaxation rate. It was found that the relaxation rates are very similar and well correspond to the prediction of phenomenological model.	chalkogenidová skla;objemová relaxace;entalpická relaxace;germanium-síra
