    "abstract": "Entropy production in the initial compression stage of relativistic heavy-ion\ncollisions from AGS to SPS energies is calculated within a three-fluid\nhydrodynamical model. The entropy per participating net baryon is found to\nincrease smoothly and does not exhibit a jump or a plateau as in the\n1-dimensional one-fluid shock model. Therefore, the excess of pions per\nparticipating net baryon in nucleus-nucleus collisions as compared to\nproton-proton reactions also increases smoothly with beam energy.",
