Abstract：
The method for particle identification using dE/dx in the BES large cylindrical drift chamber has been briefly described. The performance of the particle identification using dE/dx has been given. After applying systematic effect corrections and absolute energy calibration to the dE/dx raw data, the dE/dx energy rssolution of 7.5% has been obtained for minimum ionization particles (0.4-0.5GeV /c π) in a case corresponding to 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.
