cze	Ramanova spektra a struktura skel PbO-WO3-P2O5	Byla studována Ramanova spektra skel kompoziční řady (0·5−x/2)PbO.xWO3.(0·5−x/2)P2O5 (x=0·1, 0·2, 0·3, 0·4, 0·5 and 0·6). V řadě teplotně korelovaných spekter a upravenou baseline byly identifikovány tři komponenty pomocí PCA. Byl vytvořen termodynamický model Šachmatkina a Vediščevyse čtyřmi komponentami (PbP2O6, W2P2O11, PbWO4, a WP2O8) korespondujícími se stabilními krystalickými fázemi.

eng	The Raman spectra and structure of PbO-WO3-P2O5 glasses	The Raman spectra of glasses from the compositional series (0·5−x/2)PbO.xWO3.(0·5−x/2)P2O5 (x=0·1, 0·2, 0·3, 0·4, 0·5 and 0·6) were studied. Three components were identified in the set of baseline-subtracted and temperature-corrected Raman spectra by principal component analysis. The thermodynamic model of Shakhmatkin & Vedishcheva, with four components (PbP2O6, W2P2O11, PbWO4, and WP2O8) corresponding to the stable crystalline phases, was constructed. Correlation analysis between the scores obtained by multivariate curve analysis of the Raman spectra and the equilibrium molar amounts obtained from the thermodynamic model was performed.
