An important issues in hadron spectroscopy is the identification of glueballs. The general wisdom is that QCD must have the glueballs made of gluons. The search for the glueballs has a long history . Several models of glueballs, such as the bag model, flux tube model and constituent model, have been proposed[1??5]. Moreover, the lattice QCD has been able to estimate the mass of the low-lying glueballs[6;7].
