  An expanding fireball model with two freeze-outs, which assumes that the
chemical freeze-out occurs earlier at higher temperature and the thermal
freeze-out occurs later at lower temperature, is developed and successfully
applied to fit simultaneously the hadron ratios, transverse momentum spectra of
measured hadrons and rapidity distribution of charged hadrons measured in Au+Au
collision at 200 A$\cdot$GeV by STAR, PHENIX and PHOBOS collaborations. The
quality of all the fittings is very good and the resulting parameters are in
agreement with published values.
