Abstract：
Using the BES data collected at √ S=4.03GeV.the QED processes of e ⁺e ^－→e ⁺e ^－,μ ⁺μ ^－have been studied. Our measurements agree with the QED prediction,and luminosities obtained from these two final states are compatible at a level of 4%.The total integrated luminosity of 23.1pb ^－1was given for all data collected at this energy region from the calculation.
