Abstract：
In this paper, we suggest that the gluon is hadronized by first splitting into a quark-antiquark pair. The final hadrons are produced by the color interactions among the quarks and antiquarks. Under this assumption,the calculated average charged particle multiplicities in e⁺e^- three-jet events. The ratio of multiplicities between gluon and quark jets, and the rates of baryons in e⁺e^- three gluons events all agree well with experiments. The angular distribution of final particles can also be explained.
