  The transverse momentum distributions for hadrons in 200GeV Au-Au collision
at RHIC is calculated using a smoothed particle hydrodynamics code SPheRIO, and
are compared with the data from STAR and PHOBOS Collaborations. By employing
the equation of state which explicitly incorporate the strangeness conservation
and introducing strangeness chemical potential into the code, the transverse
spectrums give a reasonable description for the experimental data.
