We investigate the production of the Phi meson and the Omega baryon which interact weakly with hot hadronic matter, and thus their spectra reflect the early stage of the heavy ion collisions. Our analysis shows that the hadronization temperature, T_had, and the transverse flow, v_T, of the initial deconfined phase are strongly correlated: T_had + a * (v_T)**2 = 0.25 GeV, where a=0.37 GeV in the Pb+Pb collision at 158 AGeV/c. When choosing appropriate initial values of T_had and v_T from the temperature region T_had=175 +- 15 MeV, the measured Rho meson spectra was reproduced surprisingly well by the MICOR model. We have found weak influence of final state hadronic interactions on the transverse hadron spectra at m_T - m_i > 0.3 GeV.
