| 摘 要： | 对华家照提出的Fq矩的矩阶数连续化方案进行了检验,发现它不能用于真实数据的分析,对此作了改进,使它能用于真实的实验数据的分析,对400GeV/c pp碰撞产生的带电粒子赝快度分布实验数据的分析结果表明,阶乘矩的矩阶数连续崐化方法是可行的,说明在400GeV/c pp碰撞多重产生过程中可能存在多重分形行为.

| Abstract: | The method of the factorial moments Fq of continuous order suggested by Hwahas been tested.It is found that this method can not be used to analyse the real experimental data. Some improvement has been made in the method, which. can be used for the real experimental data. The analytic results for the experimental pseudorapidity distributions of charged particles produced in 400GeV/ c pp collisions indecated that the method of the factorial moments of continuous order is available. And there is seemingly multifractal behavior in the process of multiplicity production in pp collisions at 400GeV/ c. |

| Keywords: | factorial moments of continuous order negative binomial distribution maximum likelihood function method multifractal behavior. |
