Abstract：
In this paper the nonleptonic D ⁰-decays are discussed. Using Gilman and Wise's methods, we derived the effective Hamiltonian for Cabibbo-suppressed nonleptonic D ^{0^*}-decays. The rate F(D ⁰→K ⁺K ^-)/Γ(D ⁰→π ⁺π ^-)～1.26 is obtained. Some problems in this method of the calculations are discussed roughly.
