Abstract Three jets events in e⁺e^- collisions at 91.2 GeV are investigated using both HERWIG and JETSET Monte Carlo generators. The angles among the three jets are used to identify the quark and gluon jets. An analysis at the parton level is carried out to ensure the reasonableness of this method and an angular cut is ultilized to improve the purity of this identification. The multiplicity inside the identified quark or gluon jets agrees with the quantum chromodynamic predictions qualitatively.
