摘要：

The three-loop QCD corrections to the rho parameter from top and bottom quark loops are calculated. The result differs from the one recently calculated by Avdeev et al. As function of the pole mass the numerical value is given by delta rho = 3G(F)M(1)(2)/8 root 2 pi(2) (1-2.8599 alpha(s)/pi - 14.594(alpha(s)/pi)(2)).
