摘要：
By taking into account the effects of thermal motion, the transverse momentum distributions of identified charged particles produced in nucleus collisions are discussed in the context of a hydrodynamic model including phase transition. A comparison is made between the theoretical predictions and experimental measurements. The theoretical model gives a good description to the data collected in Au-Au collisions at RHIC energy of root(NN)-N-S = 62.4 GeV. For Pb-Pb collisions at LHC energy of root(NN)-N-S = 2.76 TeV, the model works well up to the transverse momentum of about pT = 1.1 GeV/c.
