摘要We use the event generator LUCIAE to analyse NA35 data of the (p) over bar and <(Lambda)over bar> yields,the transverse mass distributions and the ratio <(Lambda)over bar> (p) over bar in pp and central sulphur-nucleus collisions at 200A GeV. The results seem to indicate that NA35 data might imply the reduction of strangeness suppression in ultrarelativistic nucleus-nucleus collisions comparing to the nucleon-nucleon collision at the same energy. However, the ratio <(Lambda)over bar>/(p) over bar approaching to unity in AA collisions comparing to pp collision does not necessarily mean quark flavor symmetry.
