摘要：

The amplitudes for two-body Cabibbo allowed nonleptonic decays of D mesons are evaluated within the factorization approximation from the effective Hamiltonian including short distance QCD corrections to next-to-leading order. Annihilation and W-exchange contributions as well as final state interaction effects have been included and are in fact crucial to obtain agreement with the experimental data.
