    "abstract": "We investigate the effect of chemical freeze-out on identified particle\nspectra at 200AGeV Au-Au Collisions at RHIC, by utilizing a full\nthree-dimensional hydrodynamical calculation. The hydrodynamical code SPheRIO\nwe employed is based on the smoothed particle hydrodynamic algorithm. In order\nto describe the spectra of strange hadrons, the code has been further improved\nby explicitly incorporating the strangeness conservation and a chemical\nfreeze-out mechanism. In our model, strange hadrons such as Lambda, Xi, Omega\nand phi undergo the chemical freeze-out immediately after the hadronization,\nand their multiplicities are fixed thereafter. At a lower temperature the\nthermal freeze-out takes place for all the particles. It is shown that the\npresent model provides a reasonably good description for the spectra of\nidentified particles, in particular, considerable improvement is observed for\nthose of strange hadrons.",
