Abstract：
In this paper,by taking the confining potential with the color screening effect as a color confinement between quark and antiquark,the effect on heavy quarkonia (cc and bb) is studied.It shows that the effect may give different predictions for orbital angular momentum of high excited energy levels of ψ(cc),and make improvement in the widths of leptonic decay mode.
