Abstract：
The coupling problem of the three different intermediate processes J/ψ→ωf ₂(1270),f ₂→π ⁺π ^－and J/ψ→b ₁ ^±(1235)π ⁺,b ₁ ^±→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 f ₂and b ₁ ^±and the helicity amplitude ratios of these reactions precisely.
