    "abstract": "We propose a non-equilibrium, hadronic kinetic model for describing the\nrelative abundance of strange particles in ultra-relativistic heavy-ion\ncollisions. The energy dependence of the multiplicity ratios of charged kaons\nand lambdas to pions are studied in detail. The pronounced peak in positively\ncharged K/pi is conjectured to be due to the decreasing lifetime of a fireball\nwith an increase in beam energy above 30 AGeV. Such a behaviour may be the\nconsequence of a stronger stopping at lower beam energies. We study the\ndependence of the multiplicity ratios on energy and baryon density of the\nfireball and its total lifetime.",
