Glueball-$Q\bar{Q}$ mixing and Okuba-Zweig-Iizuka rule violation in the   hadronic decays of heavy quarkonia
  We investigate the correlations between the scalar meson configurations and Okuba-Zweig-Iizuka (OZI) rule violations in the hadronic decays of heavy quarkonia, e.g. $J/\psi$ and $\Upsilon$, into isoscalar vector meson ($\phi$ and $\omega$) and scalar mesons ($f_0(1710)$, $f_0(1500)$, and $f_0(1370)$). It shows that the dramatic change of the values of the branching ratio fraction of $\phi f_0/\omega f_0$ from low (e.g. in $J/\psi$ decays) to high energies (e.g. in $\Upsilon$ decays) will not only test the glueball-$Q\bar{Q}$ mixings, but also provide important information about the mysterious OZI-rule violations within the scalars.
