Abstract：
The three-step two-body decay process of J/ψ,J/ψ→V+X,X→P1+ Y,Y→P2+P3 is discussed using the generalized moment analysis method. The spin, parity and the ratios of helicity amplitudes of boson resonance X can be determined in terms of the measurement of the corresponding moments except a very special case.
