Abstract：
The detection efficiency corrections for the particle identification and kinematic fit selection criteria are investigated for the branching fraction measurements in ψ′decays into ωπ ⁺π ^－, b ₁π,ωf ₂(1270), ωK ⁺K ^－, ωp, φπ ⁺π ^－, φf ₀(980),φK ⁺K ^－, φp final states using 4×10 ⁶ψ′data sample collected at BEPC/BES. Based on the corrected efficiencies, the preliminary results of these decay channels have been obtained, and the "12%" rule predicted by perturbative QCD theory has been tested.
