摘　　要：The chayged particles produced in nucleus-nucleus collisions are classified into two parts. One is from the hot and dense matter created in collisions with the evolution dominated by revised Landau hydrodynamics, and the other is from leading particles. The rapidity distributions of these two parts of the particles are presented, which are then compared with the experimental measurements carried out by a CERN-LHC-ALICE collaboration in Pb-Pb collisions at √SNN = 2.76 TeV. The theoretical results are consistent with the experimental data.The chayged particles produced in nucleus-nucleus collisions are classified into two parts.
