Abstract：
In this paper,we suggest that the gluon is hadronized by first splitting into a quark-anti-quark pair.The final hadrons are produced by the color interactions among the quarks and antiquarke.By this assumption,the calculated average charged particle multiplicities in e⁺e^－→3jet events,and the ratio of multiplicities between gluon and quark jet,and the rates of baryons in e⁺e^－ three gluons events all agree well with experiments.The angle distribution of final particles can be explained.
