Abstract：
A comparison of two different fragmentation schemes in e⁺e^- annihilation is presented in this paper. After further calculations of the average number of various final hadrons and comparison with experiments, we find that the independent fragmentation scheme is in contradiction with the data whereas the string fragmentation assumption fits the data well.
