Abstract：
Based on the Monte Carlo simulation and J/ψ data of BES Ⅱ, the performance of p and in BES detector is studied, which includes the criteria for removing the secondary charged tracks and fake photons produced by the annihilation of with the materials, the energy loss and deposited energy of p and in BSC, as well as the minimum p and momentum which can be reconstructed correctly, The combined TOF and dE/dxinformation is suggested to be used for p and identification.
