摘　　要：根据e^+e^-湮没中夸克的产生律与组合律,本文计算了高能e^+e^-→h_2'反应中三种长寿命带电粒子的产额及平均带电粒子多重数<n_(ch)>,计算结果同实验相符。Based on the quark production rule and quark combination rule, the average yields of longlived charged particles and average charged multiplicities in high energy e^+e^- annihilation have been studied. The calculated yields of hadrons, average charged multiplicities and their energy dependences are all consistent with the available data.
