摘要
假设：强子－强子碰撞产生ｎ个荷电粒子的概率是Ｐｎ＝ｘＰｎ（１）＋（１－ｘ），其中适当选择参数〈ｎ〉１，〈ｎ〉２，ｋ和ｘ，可成功地描述质心能量ＧｅＶ处、全相空间的真实多重性分布．利用＝２００ＧｅＶ和９００ＧｅＶ处、质子－反质子的非单绕碰撞实验数据检验这个假设，证实了这假设很好地描述了实际情况．最后，讨论了这个假设的理论根据。
With the assumption that the probability for n-charged particles production inhadron-hadron collision isPn = xPn(1) + (1 x)Pn(2), whithin Pn(1)= andand proper choice of <n>1, <n>2, k and x, the true multiplicity distribution in full phase space can be described successfully at the centre fo mass energy GeV. Using the experimental data of non singe-diffractive collisions between proton and antiproton at centre of mass energies of 200 and 900GeV, the supposition had beenexamined and confirmed: it is very good to describe the facts. Had been discussed the theoretical bases of supposition.
