<hidden TTP94-14  O(\alpha\alpha_s\ln m_t^2) non-universal Corrections to the Decay Rate \Gamma(Z\to b\bar b) > The partial decay rate $\Gamma(Z\to b\bar{b})$ is significantly
 influenced by the mass of the top quark due to electroweak radiative
 corrections.  The leading $\sim m_t^2$ and the next-to-leading
 contribution $\sim \ln m_t^2$ are known to be numerically of similar
 size.  In this work we calculate the QCD corrections to the
 logarithmic correction using the heavy top mass expansion.  The ${\cal
 O} (\alpha\as \ln m_t^2)$ corrections are of the same order as the QCD
 corrections to the quadratic top mass term, but of different sign.
