Abstract：
The uncertainty of the treatment for the beam associated backgrounds is one of the dominant errors in the previous R measurement at BES/BEPC. A new method is developed to separate the beam associated sample from the raw data, and this sample is used in tuning the parameters of the hadronic generator LUARLW. This improvement can decrease the systematic error of the selection efficiency of hadronic events, and improve the precision of the R value.
