• The cut of phase space , particle type , average multiparticle , etc . no dynamical fluctuation has been observed through event factorial moments analysis
  可见，通过对事件阶乘矩erraticity的分析，根本就观测不到任何动力学起伏。
• We find that the erraticity of event factorial moments is still dominated by the statistical fluctuations though the multiplicity is already several hundreds and several thousands

  在非对心碰撞中，初始坐标空间中的方位角不对称性将导致末态粒子相对于“反应平面”的角依赖性。微观上讲，末态动量空间的大的各向异性来源于碰撞最初阶段的大量的再散射。
• After a careful comparison we found : ( 1 ) rotating the coordinate system around the z - axis for each event is necessary for the relaxation of the correlation between thrust ( or sphericity ) major - minor frame and the direction of the first hard gluon emission . ( 2 ) the horizontal factorial moments ( hfm ) are equivalent to the vertical ones ( vfm ) only after cumulant - variable transformation . therefore , in the study of nonlinear phenomena in high energy collisions the hfm can be used only in combination with the cumulant variables
  工jlnfy4ww ； 6标系与发射第一个硬胶子之间的关联效应，从而观察到全部强度的动力学起伏；证明了：只有在引入累积变量以后，横向矩才等于纵向矩，从而也才等效于几率矩，困而只有在这时，横向矩才能被使用；论证了：对eb对撞末态粒子系统动力学起伏的研究只能在全相空间进行，而不能用限定的相空间，因而只能采用丢掉最初的一个或几个点的方法消除动量守恒对相空间标度特性的影响。
