摘要：
Abundances and m(perpendicular to)-spectra of strange and other hadronic particles emanating from central 158-200 A GeV reactions between nuclei are found to originate from a thermally equilibrated, deconfined source in chemical non-equilibrium. Physical freeze-out parameters and physical conditions (pressure, specific energy, entropy, and strangeness) are evaluated. Properties of the source we obtain are as expected for direct hadron emission from a deconfined quark-gluon plasma phase.
