摘要：
We present a comparison of the strong couplings of b, c, and light (u, d, and s) quarks derived from multi-jet rates in flavor-tagged samples of hadronic Z(0) decays recorded with the SLC Large Detector at the SLAC Linear Collider. By comparing the rates of 3-jet events in these three samples we have extracted the Preliminary values of: a(s)(uds)/a(s)(all) = 0.96+/-0.03(stat.)+/-0.04(syst.)+/-0.02(theory), a(s)(c)/a(s)(all) = 1.16+/-0.11(stat.)+/-0.10(syst.)+/-0.07(theory), a(s)(b)/a(s)(all) = 0.98+/-0.04(stat.)+/-0.08(syst.)+/-0.02(theory).
