摘　　要：用蒙特卡洛方法研究了在部分子层次上从 91 .2 Ge Ve+ e-碰撞产生的 2 -喷注事件中被区分出来的夸克喷注和反夸克喷注中的动力学起伏 ,结果发现在这 2种喷注中都存在一个转变点 。The dynamical fluctuations inside the quark and antiquark jets, being identified at parton level from the 2-jet events in e +e - collisions at 91.2 GeV, are studied separately using the Monte Carlo method. The results show that a transition point exists inside both of these two kinds of jets, thus a scale for determining the visible jet in experiments is obtained.
