Abstract：
We have derived a modified expression for the QCD effective coupling constant totwo-loop order It amounts to adding the terms of higher order than Int/t which areindependent of the renormalization scheme to the usual expression. On the basis of theresult we proposed a in momentum and coordinate representation respectively, singleheavy quark potential which has the properties of both asymptotic freedom and as-sumed linear confinement, and obtained the slope of the linear potential at large dis-tances k=4π∧²/(33--2N_f). We bound that it is possible to determine the potential bymeans of the single parameter ∧ if the quark flavor number N_f is specified in abvance.
