Abstract：
The mean production probability of light flavor u, d and s quarks in the pp and p p reaction is calculated and discussed in this paper. It is found that the production probability depends on the energy and type of the reaction. As a result, the average yields of directly hadrons, the asymmetry of isospin, and the ratio of particle to antiparticle are all dependent on the energy and type of the reaction. In particular, we find that the ratio of banyon to antibaryon in pp reactions is larger than 1, which is consistent with the experiment results of heavy ion colliding.
