    "abstract": "We have used the event generator LUCIAE to analyse NA35 data of the $\\bar p$\nand $\\bar{\\Lambda}$ yields, the ratio $\\bar{\\Lambda}/\\bar p$, and the\ntransverse mass distributions of $\\bar p$ and $\\bar{\\Lambda}$ in pp and central\nsulphur-nucleus collisions at 200A GeV. The NA35 data could be reproduced\nreasonably if one assumes that the s quark pair suppression factor and concerns\nin nucleus-nucleus collisions are larger than the nucleon-nucleon collision. It\nseems to indicate that NA35 data might imply the reduction of strangeness\nsuppression in ultrarelativistic nucleus-nucleus collisions comparing to the\nnucleon-nucleon collision at the same energy. However, the ratio\n$\\bar{\\Lambda}/\\bar p$ approaching to unity in AA collisions comparing to the\npp collision does not necessarily mean a flavor symmetry since hadronic\nrescattering plays a role as well.",
