摘要：

We propose to study the impact parameter dependence of the (A) over bar/(p) over bar ratio in Pb(160A GeV) + Pb reactions. The (A) over bar/(p) over bar ratio is a sensible tool to distinguish between hadronic cascade models and hydrodynamical models, which assume chemical equilibrium and incorporate a possible phase transition to a quark-gluon plasma. [S0556-2813(99)50204-5].
