Abstract：
From the simple physical picture of quark combination model, we obtain the generate probabilities of various particles and relative ration in e ⁺e ^－→q ₀q ₀→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.
