Abstract：
The decays t→cV(V= Z,γ, g) induced through loop processes are calculated in Topcolor-Assisted Multiscale Technicolor model. We find that the extended technicolor interactions provide the main contribution to these decays, and the total contribution can enhance the Standard Model branching ratios by as much as 5 to 6orders of magnitude, i.e., B(t→cZ)～10^－6,B(t→cβγ)～^10－7,B(t→cg)～10^－5,for the favorable parameter values.
