The authors present recent results on single particle transverse momentum distributions of pions, kaons, and protons, measured in CERN Experiment NA44, of 200A{center_dot}FeV/c S+S and 158A{center_dot}GeV/c Pb+Pb central collisions. By comparing these data with thermal and transport models, freeze-out parameters like the temperature T{sub fo} and the chemical potentials ({mu}{sub q}, {mu}{sub s}) are extracted and discussed.
