摘　　要：本文引用了熵指数μq来描述3.7 A GeV16O-AgBr作用产生簇射粒子的事例间阶乘矩涨落,给出了所有事例的平均阶乘矩、个别事例的阶乘矩、及阶乘矩的分布,最后得出阶乘矩分布的矩和熵指数,结果表明3.7A GeV 16O的事例间的阶乘矩涨落与超高能下有相似的结果,推断可能有同一物理过程。The entropy index, μq, is introduced in this paper to describe the fluctuation of factorial moments in event space. The averaged factorial moments of events, the factorial moments of certain event, and the distribution of the factorial moments of 3.7 A GeV 160-AgBr interaction is also studied. The results show that the event factorial moments fluctuation is the same as the results at the uhrarelativistic energies, which suggest that the same physics process is involved.
