Abstract: The data samples for the measurement of R values, hadron form factors, the line-shape scan of the high mass charmonium family and new states have been taken in the full energy region that BEPCII can reach, namely between 20 and 46 GeV. The present status of R value measurement is briefly reviewed.

Key words: R value measurement, the Standard Model, data analysis, Monte Carlo simulation
