| Abstract: | OZI rule violations were investigated in the decay of J/Ψ mesons,and an estimate of the contributions from intermediate states to the decay branching ratios was given.OZI rule violations in the J/Ψ meson decay processes were discussed.The calculation results for J/Ψ→f0φ decay are in agreement with the experimental results,which shows there are large OZI rule violations in those decay processes. |

| Keywords: | OZI rule intermediate virtual mesons decay branching ratio |
