摘要：

We study the energy dependence of collective (hydrodynamic-like) nuclear matter flow in (400-1970)A MeV Ni + Au and (1000-1970)A MeV Ni + Cu reactions. The flow increases with energy, appears to reach a maximum, and then to decrease at higher energies. A way of comparing the energy dependence of flow values for different projectile-target mass combinations is introduced, which demonstrates a more-or-less common scaling behavior among flow values from different systems.
