纵向矩 meaning in Chinese

longitudinal moment

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。
