摘要：

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