  levy stability
     In order to investigate the intermittency behaviour in high energy collisions using the Levy stability theory, it is necessary to develop a method for the analytical calculation of Levy exponent. In view of this, the random cascading αmodel is refined to make the expression of the probability ω of elementary division linear. Using this model, the Levy exponent is calculated analytically.
     为了用Levy稳定性理论研究高能碰撞多重产生中的间歇行为,除了采用蒙特卡罗模拟外,有必要找到一种能对Levy指数作解析计算的方法.为此,改进了随机级联α模型,使其中基元分割几率ω的表达式是线性的.用这一模型,解析地计算了Levy指数,得到了与理论预言相一致的结果;

In order to investigate the intermittency behaviour in high energy collisions using the Levy stability theory, it is necessary to develop a method for the analytical calculation of Levy exponent. In view of this, the random cascading αmodel is refined to make the expression of the probability ω of elementary division linear.Using this model, the Levy exponent is calculated analytically. The results are consistent with the theoretical prediction. The analytical expression for the moments of ω is obtained. In order to compare the present model with the original one, the MC simulation is done for both models, and the intermittency indices are calculated,showing that both models are practical and reliable.
