Abstract：
In virtue of the simple physical picture of quark combination model, we determine the dependence of anti-particle to particle ratios on the mean production probability of anti-quarks and quarks. The ratios of various anti-particle to particle at relativistic heavy ion collisions are calculated without any additional assumption, which are consistent with the experiment results of the Au+Au collision at √S_NN=130GeV measured by STAR collaboration at RHIC. These results provide a basis for further studies of particles ratios in relativistic heavy ion collisions.
