摘要：
Pattern formation in planar nematic with cylindrical director field configuration in the conductive regime of electrohydrodynamic convection has been studied experimentally. The rotating roll pattern with axial symmetry has been found above the threshold. For frequency of ac electric field lower than the Lifshitz point, the roll pattern is divided into two systems of rotating oblique rolls so that their superposition looks like sunflower. The rotation frequency of rolls has been measured as a function of ac electric field frequency.
