Abstract：
The hadronic decay processes J/ ψ→V ₁+X、X→ V ₂+ V ₃,V ₂,V ₃→2P (or 3P) (where V _iand P stand for the vector arid pseudoscalar meson, respectively) are discussed in this paper. For the intermediate state X with various spin-parity J ^P, the corresponding helicity formalism of the angular distributions are presented. They are helpful for determining the spin-parity of the intermediate state in the above processes by using the J/ ψevents
