摘　　要：根据非饱和势模型对ｅ＋ｅ－→ｑｑ→ｈ’ｓ过程作了全面的Ｍｏｎｔｅ－Ｃａｒｌｏ模拟．采用一个近似于快度均匀分布的相对纵动量分布，并利用一个与非饱和势模型相一致的方法处理了重粒子衰变．最后把Ｍｏｎｔｅ－Ｃａｒｌｏ模拟结果同２９和３５ＧｅＶ的实验作了比较．Monte-Carlo simulations of the process e+e-→qq→h's according to the unsaturated model were performed.A kind of longitudinal momentum distribution similar to the constant rapidity distribution in momentum sampling and a particular method to deal with decays of hadrons which contain heavy quarks were used.At the end of this paper we compare results of our MC simulations to experiments.
