Abstract：
The Beijing Spectrometer Ⅲ (BESⅢ) is a general-purpose detector used for the study of τ-charm physics at the Beijing Electron-Positron Collider Ⅱ (BEPCⅡ). This paper presents our studies of the dE/dx measurement in the drift chamber of BESⅢ, which is important for the identification of charged particles. Corrections applied to the dE/dx measurement in data reconstruction are discussed. After our current dE/dx calibration, a resolution of about 6% has been obtained for minimum ionization particles, and a 3σ K/π separation is obtained for momenta up to 760 MeV/c. These results meet the design goals of the BESⅢ drift chamber.
