                                 Abstract:The proposed hadronic transport model for rescatterting of pion is used to investigate the K+/π+ ratio in p+p,p+Au and Si+Au reactions at AGS energy(14.6AGeV/c).Experimental evidence of increasing continuously of the K+/π+ ratio from p+p to p+Au to Si+Au at similar incident energy per nucleon is reproduced reasonablely.The experimental fact of K+/π+ ratio at CERN energy is comparable with corresponding result at ACS energy,is reproduced as well.
