cze	Viskozita selenové taveniny	Viskozita selenového skla, podchlazené taveniny a taveniny byla měřena pomocí metod penetrační a rotační viskozimetrie a pomocí metody transverzálního toku. Získané výsledky byly porovnány s dříve publikovanými daty a byly diskutovány v souvislosti s teorií Adama a Gibbse.	chalkogenidy;entropie;viskozita
eng	Viscosity of selenium melts	Viscosity of selenium was measured by using three different methods; the penetration method, the parallel-plate method and the rotating bob method. The experimental data are compared with numerous viscosity data reported previously. Temperature dependence of all these results are expressed by the Adam-Gibbs (AG) and the Vogel–Fulcher–Tamman (VFT) equations. The nature of the glass transition and the significance of adjustable parameters of AG and VFT equations have been discussed.	Chalcogenides;Entropy;Viscosity
