【摘要】 用蒙特-卡洛模拟方法对纵向阶乘矩和横向阶乘矩进行了比较和研究。发现:在一般情况下,只有在引入累积变量后,纵向阶乘矩才与横向阶乘矩相等。因此,在高能碰撞非线性现象(间歇和分形)的研究中,只有采用了累积变量时,才能使用横向阶乘矩进行计算。另一方面,在单事件分析中,使用横向阶乘矩进行计算是有意义的。更多还原

【Abstract】 The difference in the horizontal and vertical factorial moments is compared and studied using Monte-Carlo simulation.It is shown that the horizontal and vertical factorial moments are equivalent only when they are used in combination with the cumulant variables.Therefore,in the study nonlinear phenomena in high energy collisions the HFM can be used only in combination with the cumulant variables.On the other hand,the HFNM is in its own right useful in single-event analysis.更多还原
