摘要 按照夸克组合模型,通过分析给出e^+e^-→q00→h's过程轻味夸克jet事例中各种粒子的产生几率以及相对比值.给出奇异、非奇异粒子多重数比率γ与奇异抑制因子λ之间的关系,不需要假设奇异抑制因子改变,能够解释粒子比率增大的实验. From the simple physical picture of quark combination model, we obtain the generate probabilities of various particles and relative ration in e^+e^→q0-↑q0→h′s process, and find that the relationship between the ration of strange hadron to unstrange hadron γ and the strangeness suppression factor λ. Our results can be used to explain particle ration enhancement observed in experiments without assumption of strangeness suppression factor enhancement.
