Abstract：
The contributions of Pseudo-Goldstone Bosons in one generation technicolor model to the rare decays t→cV(V= Z,γ,g) are calculated.We find that these new contributions can enhance the SM branching fractions by as much as 3—4 orders of magnitude.The branching fractions can reach to:B(t→ cg)～10 ^－6,B(t→cZ)～10 ^－7,B(t→cγ)～10 ^－8for the favorable values of the parameters.
