　　报告内容：The Q-cumulant analysis is performed using the data of a single event. The analysis is done for several different physical systems: a single image of the expanding ultra cold Fermi gas of neutral {6}^Li atoms at 860 G, an AuAu collision at sqrt{s_NN} = 200 GeV, a vHLLE+UrQMD model of an AuAu collision at sqrt{s_NN} = 11.5 GeV, a SMASH model of an PbAu collision at sqrt{s_NN} = 17.3 GeV, a CMS like simulated PbPb event at sqrt{s_NN} = 5.02 TeV, and for a simulated event with the isotropic emission of particles. In all of these cases, a proper cumulant ordering among the v_{2} harmonics v_{2}{2k}≳ v_{2}{2(k + 1)} up to high order 2k is seen. That splitting enabled calculation of the corresponding hydrodynamic probes calculated from the measured v_{2}{2k}. The cumulant splitting in a single event has been observed for the first time.
