cze	Entalpická relaxační kinetika skla GeTe4	Pomocí DSC byla studovna entalpická relaxace infračerveného chalkogenidového skla GeTe4. Relaxační chování bylo popsáno fenomenologickými modely TNM a AGS. Výsledné fity byly získány křivkovým fitem a porovnány s výsledky nefitovacích metod.

eng	Enthalpy relaxation kinetics of GeTe4 glass	Differential scanning calorimetry was used to study enthalpy relaxation kinetics of the GeTe4 infrared chalcogenide glass. The relaxation behavior was described in terms of the phenomenological Tool-Narayanaswamy-Moynihan (TNM) and Adam-Gibbs-Scherer (AGS) models. The direct curve-fitting procedure was found to provide the most accurate results under the assumption that high-quality DSC data are obtained and the correct pre-fitting treatment is applied. The recently developed novel evaluation of Delta h* from CR cycles and the improved simulation-comparative methodology were then found to provide the best results out of the tested non-fitting methods.
