  "abstract": "Based on the data of BES and Belle, the production of $D\\bar{D}$ in the $e^+e^-\\to D\\bar{D}$ scattering process is studied in this paper. We analyze the continuum and resonant contributions in the energy region from 3.7 to 4.4 GeV. In the $\\chi^2$ fit to data, we obtain the resonance parameters of $\\psi(3770)$, the branching ratio of $\\psi(3770)\\to D\\bar{D}$ decay by confronting the data to the theoretical formula where both the contributions of the resonances, continuum and interference effects are included. We obtain the branching ratio of $\\psi(3770)\\to D\\bar{D}$ decay is $97.2%\\pm 8.9%$, as well as the branching ratio of $\\psi(4040)$, $\\psi(4160)\\to D\\bar{D}$ decays.",
