摘要：
The effect of different secondary collisions on the increase of the K+/π+ ratio in relativistic heavy-ion collisions is analyzed based on the participant-spectator picture. It is shown that the effect of secondary collisions is not enough to explain the observed increase of the K+/π+ ratio. © 1990.
