Description	Monte Carlo simulacemi byla studována struktura systému tuhých disků s cílem odhalit a charakterizovat strukturní změny v oblasti tuhnutí/tání. Byl definován jistý tvarový factor a aplikován na Voronojovy buňky, který dokáže tyto změny charakterizovat. V oblasti přechodu vykazuje tento factor druhý lokální extrem. (cs) The fluid of two-dimensional hard disks is investigated over a range of densities by Monte Carlo simulations in order to detect and characterize structural changes which take place when the condition of freezing/melting is approached. We use the Voronoi tessellation and a certain shape factor which turns out to be a clear indicator of the presence of different underlying sub-structures (domains). Close to the freezing condition the probability distribution of the shape factor develops a second distinct maximum corresponding to a predominant presence of near-regular hexagons, whereas the original peak, having its origin primarily in pentagons and distorted hexagons, diminishes and disappears at melting density.
