【摘要】 利用ＣＥＲＮＮＡ２７合作组提供的ＬＥＢＣ泡室照片对４００ＧｅＶ／ｃＰＰ碰撞产生的带电粒子赝快度分布进行了测量．计算了标度阶乘矩．得出间歇指数随矩阶数的增加而增加，随平均多重数的增加而变小；反常分形维数ｄｑ随ｑ的增加而增加．这表明在强子－强子碰撞中多粒子产生具有自相似级联的性质．更多还原

【Abstract】 The pseudorapidity distributions for charged particles produced in pp collisions at 400GeV/c have been measured by using the LEBC films offered by CERN NA27Collaboration.The scaled factorial moments have been calculated.It is obtained that the intermittency exponent increases with increasing moment-order and decreases with increasing average multiplicity,the anomalous fractal dimension dq increases with q.It shows that the multiparticle production in hadron hadron collisions possesses a self-similar cascade property.更多还原
