Abstract：
The coupling problem of the three different intermediate processes (e.g., 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 heiicity amplitude ratios of these reactions precisely.
