摘要
在对相空间用非整数分割作阶乘矩分析时，由二粒子或多粒子关联所引起的非均匀因素的影响必须加以认真考虑．本文对高能碰撞末态粒子的阶乘矩在相空间进行非整数分割时的分析方法进行了仔细研究，建立了一套完整的对非整数分割下阶乘矩的分布进行修正的方法．用NA22实验组的实验数据计算，证明其方法是正确的．
Deing the factorial moment analysis with non-integer partition M of phace space, the influence of the unflat distribution of two or more particle correlations has to be considered. In this paper the analysis method on the factorial moment in the phase space of multiparticle production with non-integer partition M is studied carefully.A systematic method for rectifying FM distribuhon with non-integer partition M is developed. The calculated results with this method is checked by using NA22 data.
