Abstract：
The coupling problem of the three different intermediate processes (e.g., J/ψ→ωf₂ (1270)，f₂→π⁺π^- and J/ψ→b₁^±(1235) π^∓，b₁^±→ωπ^±) included in the hadronic decay process J/ψ→ωπ⁺π^- is discussed. The consideration of the coupling effect is very important for measuring the parameters of the resonances f₂ and b₁^± and the heiicity amplitude ratios of these reactions precisely.
