Abstract：
The method for particle identiHcation using dE/dx information from the BES large cylindrical drift chamber is briefly described. The performance of the particle identiHcation using dE/dx is given. After applying systematic effect corrections and absolute energy calibration to the dE/dx raw data, the dE/dx resolution of 7.5% is obtained for minimum-ionizing particles (0.4-0.5GeV/c 7π) with more than 30 dE/dx samples per track. This results in 3σK/π separation for momentum up to 0.65GeV/c and 3σe/π separation in a momentum range of 0.2 ≤ p ≤ 4GeV/c.
