Abstract：
The recent experimental data from TASSO and HRS collaborations for multiparticle production in high e⁺e^－ annihilation is analysed in a cylindrical bag model.It is shown that the observed approximate KNO scaling can be explained in terms of bag parameter B,which determines the hadronization probability densities proportional to the square of the materialization energy.
