Motivated by the experiments of heavy flavor physics at running LHC and upgrading Belle-Ⅱ in the future,the nonleptonic B~*→DD~*,Dρ,DK~*,πD~* and KD~* weak decays were studied in details.With the amplitudes calculated with factorization approach and the form factors of B~* ransition into pseudoscalar meson evaluated with the BSW model,the branching fractions and the polarization fractions were firstly presented.Numerically,the B_q~*→D_qD_s~* and D_qρ decays had the large branching fractions,10~8,which shoul...
