    "abstract": "We present a systematic study of the kaon to pion multiplicity ratios (K+/pi+\nand K-/pi-) in heavy-ion collisions from AGS to RHIC energy using the\nRelativistic Quantum Molecular Dynamics (RQMD) model. The model satisfactorily\ndescribes the available experimental data on K+/pi+ and K-/pi-. Within the\nmodel, we find that the strong increase of the ratios with the number of\nparticipants is mainly due to hadronic rescattering of produced mesons with\ningoing baryons and their resonances. The enhancement of K/pi in heavy-ion\ncollisions with respect to elementary p+p interactions is larger at AGS energy\nthan SPS energy, and decreases smoothly with bombarding energy. The total\nmultiplicity ratios at RHIC energy are predicted by RQMD to be K+/pi+ = 0.19\nand K-/pi- = 0.15.",
