摘要：

Elliptical energy flow in noncentral Au(11.7A GeV) on Au reactions is studied comparing results obtained in two different modes of the relativistic quantum molecular dynamics approach (mean field and cascade). The final azimuthal asymmetries in the central rapidity region are very sensitive to the pressure at maximum compression, because they involve a partial cancellation between early squeeze out and subsequent flow in the reaction plane. Analysis of elliptic flow may lead to much stronger constraints on the magnitude of pressure in ultradense nuclear matter than are available today.
