Abstract
The analytic expressions for the production cross sections of polarize d bottom and top quarks in e+e-annihilation are explicitly derived at the one-loop order of strong interactions. Chirality-violating mass ef fects will reduce the longitudinal spin polarization for the light qua rk pairs by an amount of 3%, when one properly considers the massless limit for the final quarks. Numerical estimates of longitudinal spin p olarization effects in the processes e+e--->bb(g)BAR and e+e--->tt(g)B AR are presented.
