摘要
Without the non-relativistic approximation in one-loop function, the dominating one-loop contribution to the quark-antiquark potential is studied numerically in terms of perturbative Quantum Chromo Dynamics （QCD）. For Coulomb-like potential, the ratio of the one-loop correction to the tree diagram contribution is presented, whose absolute value is about 20%. one-loop contribution should be suppressed by a factor as/α deepen the comprehension of in Cornel potential. Our result is consistent with the analysis that the to the leading order contribution.
