Abstract：
We calculate one-loop corrections to the top-quark decay width г(t→W ⁺b)from PGBs (Pseudo-Goldstone bosons) in the MWTCM (multiscale walking technicolor model). The cormctions are found so large that г(t→W ⁺b) is decreased largely. If topeolor is further introduced into MWTCM, г(t→W ⁺b) is enhanced, and the PGBs' cormctions in the topeolor assisted MWTCM may reach -7% for certain parameters in this model, which might be observable in the experiments.
