Their connections to initial condition, baryon creation, freeze-out condition and strangeness enhancement were discussed.The XXXVIIth Rencontres de Moriond "QCD and High Energy Hadronic Interactions" in Les Arcs 1800, France(03/16/2002); 4 pages, 5 figures; typos fixed, added referenceNuclear Experimenttext
