Abstract：
A method is introduced for the measurement of integrated luminosity in R scan by large-angle Bhabha events. Compared with the previous method, some improvements have been made in both events selection and determination of detection efficiency. Several methods are employed to check our results and have given compatible luminosities within errors.
