cze	Strukturní relaxace z pohledu TNM a AGS modelů	V tomto článku byla studována strukturní relaxace nekrystalických materiálů. Studium bylo provedeno na amorfním selenu, Ge2Se98, As2Se98 a poly-vinylacetátu. Dva typy strukturní relaxace ? objemová a entalpická ? byly studovány pomocí rtuťové dilatometrie a diferenciální skenovací kalorimetrie. Relaxace materiálů byla popsána na základě TNM a AGS modelů. Hlavním cílem práce bylo popsat a porovnat objemovou a entalpickou relaxaci skelného Se, Ge2Se98, As2Se98 a PVAc.	strukturní relaxace;amorfní Se;PVAc;Ge-Se;As-Se
eng	Structural relaxation in terms of TNM and AGS models	In this article the structural relaxation of non-crystalline materials was studied. The materials researched in this work were the amorphous selenium, Ge2Se98, As2Se98, and poly(vinyl acetate). Two types of relaxation ? volumetric and enthalpic ? were studied by using mercury dilatometry and differential scanning calorimetry. The relaxation of the materials studied was described on the basis of the Tool-Narayanaswamy-Moynihan (TNM) and Adam-Gibbs-Scherer (AGS) models. The main objective of this work was to describe and compare the volume and enthalpy relaxation of glassy Se, Ge2Se98, As2Se98 and PVAc.	structural relaxation;amorphous Se;PVAc;Ge-Se;As-Se
