摘要：

A potential describing the interaction between quarks is obtained by considering not only perturbative effects of QCD, but also the nonperturbative contributions via <qqBAR> and <GG> condensates. In this potential, a linear confinement type term and a new r3 term can be automatically obtained. A tendency to flatten the potential at large distance is observed and it is consistent with the phenomenologically introduced potential which gives a better fit for nucleon spectrum.
