Popis: The method of elasticity constants K 22 and K 33 determining for nematic-cholesteric mixtures of liquid crystals from the data of electrooptical measurements are described. The theoretical model and experimental results shows that it is necessary to take into consideration the influence of surface forces on threshold voltages of cholesteric-nematic transition.
