摘　　要：By employing the quantum hydrodynamic model for electron ion dust plasma, we derive a dispersion relation of the quantum dusty plasma. The effects of the dust size distribution on the dispersion relation in a cold quantum dusty plasma are studied. Both analytical and numerical results are given to compare the differences between the dusty plasma by considering the dust size distribution and the mono-sized dusty plasma. It is shown that many system parameters can significantly influence the dispersion relation of the quantum dusty plasma.By employing the quantum hydrodynamic model for electron ion dust plasma, we derive a dispersion relation of the quantum dusty plasma.
