Abstract：
We calculate the new contribuhons to the charmless B decay B→X_sη′ via the QCD gluon anomaly and the enhanced b→sg decay due to the charged technipions appeared in Technicolor Model. Widen the considered paraxneter space the new physics contribuhon can result in a large enhancement to the inclusive η′ produchon and in tUrn to account for the CLEO data of Br(B→η′X_s).
