| 摘 要： | 从相对论重离子碰撞的非均匀集体流理论出发,分别讨论AGS、SPS和RHIC能区的净质子分布特征.与以前计算净质子分布不同的是,考虑了在相对论重离子碰撞中重子数守恒,通过重子数守恒限制,可以对RHIC能区的净质子分布在远离中心区的快度分布进行预言.

| Abstract: | Based on non-uniform flow model（NUFM） in relativistic heavy-ion collisions, the rapidity distribution features in the whole AGS, SPS and RHIC energy regions are discussed respectively. Compared with NUFM calculation before, the influence of baryon number conservation is considered at this time. It is found that the prediction of rapidity distribution during the large rapidity region is available by using the constraint of baryon number conservation. |
