摘要：

We report on a measurement of the mean charged-particle multiplicity of jets in dijet events with dijet masses in the range 80-630 GeV/c(2), produced at the Tevatron in p(p) over bar collisions with roots = 1.8 TeV and recorded by the Collider Detector at Fermilab. The data are fit to perturbative-QCD calculations carried out in the framework of the modified leading log approximation and the hypothesis of local parton-hadron duality. The fit yields values for two parameters in that framework: the ratio of parton multiplicities in gluon and quark jets, r = N-partons(g-jet)/N-partons(q-jet) = 1.7 +/- 0.3, and the ratio of the number of charged hadrons to the number of partons in a jet, K-LPHD(charged) = N-hadrons(charged)/N-partons = 0.57 +/-
