| 摘 要： | 用蒙特–卡洛模拟研究了多重数分布(多重数在事件空间中的起伏)对高能碰撞中erraticity行为的影响,并和NA27实验数据的结果进行了比较.证明了erraticity现象对多重数起伏不敏感.对于低的平均多重数,即使各个事件之间的多重数起伏不定,这一现象仍然主要由统计涨落决定.

| Abstract: | The influence of multiplicity distribution (fluctu ation of multiplicity in the event space) on the erraticity behaviour in high en ergy collisions is investigated via Monte Carlo simulation and compared with the experimental results from NA27 data. It is shown that, the erraticity phenomeno n is insensitive to the multiplicity fluctuation. When the average multiplicity is low this phenomenon is dominated by the statistical fluctuations, also in the case of multiplicities fluctuating from event to event. |
