Abstract：
In this paper we introduce the annihilation terms decribing transitions q _iq _i→q _jq _jand q _iq _i→(gg) and consider the SU(3) breaking effect for these terms.We discuss the mixing mechanism of η,η′and ι and obtain the quark and gluon content of η,η′and ι.At the sametime we introduce EPCAC (Extended Partially Conserved Axial-vector Current) hypothesis and examine η,η′and ι decays in two photons.We calculate yet the ratio R ₁=Γ(J/ψ→γη′)/Γ(J/ψ→γη) and R ₂=Γ(J/ψ→γη′)/Γ(J/ψ→γι) and point out the experimental restriction for the pure glueball mass.
