    By analyzing the large angle Bhabha scattering events selected from the data samples collected in the center-of-mass energy range from 3.660 to 3.897 GeV with the BES-Ⅱ detector at the BEPC collider in December 2003, we measured the integrated luminosities of the data samples. The total integrated luminosity of the data samples is(5550.96±13.56±108.24)nb-1.
