摘　　要：利用改进的多重分形矩分析了４００ＧｅＶ／ｃｐｐ碰撞多重产生的分形行为．计算了广义维数Ｄｑ（ｑ＝２－５），并与由标度阶乘矩方法得到的结果作了比较．结果表明观察到了多重分形特征．对ＦｕｊｉｏＴａｋａｇｉ提出的分形分析方法作了探讨．The fractal behaviour of multiplicity production in 400 GeV/c pp collisions is analyzed using the modified multifractal moments.The generalized dimensions Dq,q= 2 - 5,are calculated.A comparison with the results obtained by the method of scaled factorial moments has been made. The results show that the multifractal character is observed.The fractal analysis method proposed by Fujio Takagi has been tested.
