摘要
末态粒子相空间存在着各种非均匀因素．本文介绍了用阶乘矩能够消除统计起伏，证明引入累积变量后可使粒子数的分布变得均匀；
There are many uneven factor in the phase space of multi-particle.The method of removing statistics fluctuation with factorial moment was introduce and the cumulant variable able to even for distribution of multiparticle production was proved.The work also give the method to minmize of connected effect.
