摘要：

Based on the bracnhing fractions of J/psi-->VP, gammaP quoted in PDG-2000, we reexamined the quark content of pseudoscalars. If there is no gluonium content in eta and eta', the mixing angle theta(p)=(-19.18+/-0.90)degrees. We also present a discussion for DOZI contribution, SU(3) breaking and scalar-meson mixing.
