Abstract：
LUCIAE3 .0 model was used to simulate the relativistic heavy-ion collisions, namely C+C,Si+Si and Pb+Pb, which were already performed experimentally by NA49 collaboration. The simulated results of rapidity and transverse momentum distributions of all kinds of hadrons were compared with the NA49 data and found that they can fit the experimental data mostly. The kinetic temperature was deduced by the thermal fits to the transverse mass distributions of hadrons . It is found that the temperatures of light systems or hadrons fit the experimental data well, however, those of heavy systems or hadrons deviate much from the data, which probably because that LUCIAE3 .0 doesn' t include the information of QGP phase transition.
