To investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sampl., distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII col.ider in the year 2010. By anal.zing the l.rge angl. Bhabha scattering events, we measure the integrated l.minosity of the data sampl. at each center-of-mass energy point. The total.integrated l.minosity of the data sampl. is 76.16±0.04±0.61 pb^-1, where the first uncertainty is statistical.and the second systematic.
