In this paper, the nonperturbative corrections to the one-gluon-exchange potentential is studied. The results show that it is essential to adopt covariant gauges for the QCD vacuum gluon fields in order to obtain a gauge-invariant nonperturbative corrections. The new forms of the nonperturbative corrections to the one-gluon-exchange potential are presented.
