英文摘要	The production rates and the inclusive cross sections of the isovector meson pi(0), the isoscalar mesons eta and eta'(958), the strange meson k-s(0) and the lambda baryon have been measured as functions of scaled energy in hadronic events, two-jet events and each jet of three-jet events from hadronic z decays and compared to monte carlo models. the analysis is based on 3.7 million hadronic events collected with the aleph detector at lep at a centre-of-mass energy of root s = 91.2 gev. the jetset modelling of the gluon fragmentation into isoscalar mesons is found to be in agreement with the experimental results. herwig fails to describe the k-s(0) spectra in gluon-enriched jets and the a spectra in quark jets.
