摘　　要：计算了人工色荷电ＰＧ玻色子和对稀有衰变过程中单举产率的贡献．计算结果表明：ＱＣＤ胶子反常和人工色新物理贡献能够提供较大的分枝比，以解释ＣＬＥＯ实验结果．We calculate the new contribuhons to the charmless B decay B→Xsn viathe QCD gluon anomaly and the enhanced b→sg decay due to the chargedtechnipions appeared in Technicolor Model. Widen the considered paraxneter space thenew physics contribuhon can result in a large enhancement to the inclusive η'produchon and in tUrn to account for the CLEO data of Br
