Abstract：
In this paper,the effect of different secondary collision on the increase of the K⁺/π⁺ ratio in RHIC is analyzed based on a participant-spectator picture,using Monte Carlo simulation.Our results show that the increase of the K⁺/π⁺ ratio resulting from the secondary collisions alone is insufficient to explain the experimentally obtained result.
