摘要：

The <t(t)over bar> system allows a truly perturbative treatment of the potential. Completing previous computations, we calculate the contributions of QCD box graph corrections, which make the ''relativistic'' O(alpha(4)) corrections in the non-Abelian case differ from the well known corrections of the same order in QED.
