Abstract：
We calculate the hadron multiplicities and the momentum spectra of π^±,K^±,p/p in e⁺e^－→q+ng→hadrons for the case where the color separate singlet connections occur among the final partons q+ng with the help of JETSET event generator. We compare the results with those obtainted from the traditional color flow models and the available experimental data. The comparisons show that the momentum spectra obtained in the case of C-weight have a singnificant deviation from the data.,whereas those obtained in the case of T-weight are consistant with the data. The results from the case of T-weight are also consistant with those from the color flow model in most cases,and for proton, are even better than the later as implemented in default JETSET compared with the data.
