The event generator LUCIAE has been used to simulate relativistic nucleus-n
ucleus collisions. The strange meson K (0)(S), and strange baryons Lambda a
nd <(Lambda)over bar> production in S+W central collisions at 200A GeV has
been analyzed, The transverse mass spectrum for them and relative productio
n rates of strange meson to strange baryon are obtained and compared to the
data of experiments.
