摘      要：The Relativistic Vlasov-Uehling-Uhlenbeck(RVUU)model is used to study the properties of pi-ons and kaons produced in heavy ion *** include the nuclear medium effect on kaon and pionin the model,and simulate pion production and subthreshold kaon production in Kr+Zr reactions at 1GeV/*** calculated results show that the attractive pion optical potential changes the final-state pionmomentum spectrum,enhancing the yield of pions with low transverse *** the same ti1e it alsoincreases the kaon abundance and modifies the kaon momentum distribution.
