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標系與發射第一個硬膠子之間的關聯效應，從而觀察到全部強度的動力學起伏；證明了：只有在引入累積變量以後，橫向矩才等於縱向矩，從而也才等效于幾率矩，困而只有在這時，橫向矩才能被使用；論證了：對eb對撞末態粒子系統動力學起伏的研究只能在全相空間進行，而不能用限定的相空間，因而只能採用丟掉最初的一個或幾個點的方法消除動量守恆對相空間標度特性的影響。 -
