摘　　要：对 40 0GeV/cPP碰撞多粒子产生的实验数据作 (赝 )快度隔的不稳定性分析 .计算了华家照等人提出的类熵量Sq 和 q。发现Sq 和 q 明显地偏离于1,其中 1nSq 随 q的变化有较好的线性行为 .而 1n q 随 q的变化只有近似的线性行为 .对用FRITIOF模拟产生的事例样本作同样的计算 。The erraticity analysis of the pseudorapidity gaps is performed for the experimental data of multiparticle production in pp collisions at 400GeV/c.The entropy-like quantities S q and  q which have been proposed by Hwa et al .are calculated. It is found that S q and  q deviate significantly from 1. The 1nS q versus q has a quite linear behavior ,but the 1n q versus q has only an approximate linear behavior. The same calculations are performed for the event sample simulated using FRITIOF program. The results have a rather large deviation from experimental data.
