\\  {\em A precision of $10^{-6}$ on $\sin^2\theta_W^{eff}$ is a reasonable goal for the measurement of the leptonic weak mixing angle at TLEP}  An electroweak correction of great interest is the vertex correction to the $b$ partial width, which affects $\Gamma_Z$, $R_\ell$, the peak hadronic cross-section and, most sensitively, $R_b \equiv \frac{\Gamma_b}{\Gamma_{had}}$. $R_b$ was measured at LEP and SLC by tagging $b\bar{b}$ by the presence of one tagged $b$-jet and the efficiency was controlled by double tag. The SLD detector at SLC was the most efficient by the double effect of having a more precise detector, and the beam spot being smaller, thus allowing a more precise determination of the impact parameter of secondary hadrons. We expect the experimental conditions to be similar to LEP with the exception that the beam size at the IP is smaller in all dimension, thus the $b$-tagging abilities
