| 摘 要： | 对CERNNA35组公布的实验数据所显示的碰撞特点进行了分析。指出弥散D与平均多重数的比值为一常数，与入射能量、快速窗口无关的特征可由几何模型解释，但与靶质量无关的特点不能由纯几何得到有力的证明。指出纯几何模型在定量上与实验数据有偏差。利用多源模型进行了计算，获得了与实验数据符合得很好的结果。

| Abstract: | The feature of impact parameter given by NA35 collabortion is analysed. The feature of the size of D/ independenting of the incident energy, and the rapidity window size is also analysed by using a geometry model, but the invariant of D/ on incident energy can't be studied with geo metric analysing. The deviation of pure geometric model with the data is analysed by using the multi source model. |
