Description	Teplotní posuv R-čáry v keramikách zůstává prakticky identický jako v monokrystalu SrTiO3. To ukazuje, že vnitřek zrn v keramikách má stejné vlastnosti jako kvantové paraelektrikum, což souvisí se zobecněným přístupem v rámci modelu, nedávno navrženého k popisu polarizační odezvy granulovaných materiálů s vysokou permitivitou (cs) However, the temperature shift of the R-line in ceramics remains practically identical to that for SrTiO3 single crystals, in which R-line shifts with tempereature is Δν1/ε´ω2TO1. This indicates that the bulk of the grains in ceramics exhibits properties to SrTiO3 quantum paraelectric, which agrees with the %22generalized brick-wall%22 approach developed recently to describe polarization response of granular high permitivity materials However, the temperature shift of the R-line in ceramics remains practically identical to that for SrTiO3 single crystals, in which R-line shifts with tempereature is Δν1/ε´ω2TO1.
