Abstract：
The enhancement of K⁺/π⁺ ratio in the high energy heavy-ion collision is believed to be a possible signature of the quark gluon plasma.Based on the Participant Nucleon Model and the concept of the formation time of secondary particles,the K⁺/π⁺ ratio in the central collision of Si(14.5GeV/c) and Au are calculated by Monte Carlo simulation.The following secondary collisions are considered.πN→K⁺Y、ππ→KK and the single charge exchange reaction between pions and nucleons.The calculation results show that the increased K⁺/π⁺ ratio caused by these secondary collisions is not enough to explain the experimental data observed by the E802 group at BNL.
