把非均匀纵向流模型推广到包括横向膨胀流 ,并计算K介子 ,Λ和质子的快度分布 .这些模型的计算结果能较好地解释CERN SPS 2 0 0AGeV c能量下S S碰撞以及 1 58AGeV c能量下Pb Pb碰撞的实验结果 .并且能够自然地解释实验中出现的中心下凹 (centraldip)现象 . The non-uniform longitudinal flow model is generalized to include the lateral expansion flow and the fast distributions of K meson, Λ and proton are calculated.The calculation results of these models can well explain the SS collisions at CERN SPS 200 OeVe c energy, The experimental results of Pb-Pb collisions under energy and the spontaneous interpretation of the centraldip phenomenon that occurred during the experiment.
