摘要：

Possible effects of resonance production on the meson inclusive distribution in the fragmentation region are investigated in the framework of the parton recombination model. From a detailed study of the data on vector-meson production, a reliable ratio of the vector-to-pseudoscalar rates is determined. The authors examine the influence of the decay of the vector mesons on the pseudoscalar spectrum and find the effect to be no more than 25% for x>0.5. The normalisation of the nonstrange antiquark distributions are still higher than those in a quiescent proton.
