英文摘要	The BES II Muon Counter(MUC) performance is carefully studied. The MUC cluster positions and the magnetic fields in the coil and iron york of BES II are calibrated by dimuon events collected at J/phi and phi(2S) peak energies. With these calibration constants, the MUC raw data are re-reconstructed, the offsets of hit-positions in r - phi plane are diminished, and a better resolution is achieved. The charge-division algorithm to determine the hit position in z direction is modified, which improves the z resolution to 5cm for the first layer of MUC. All these modification will make the data analyses involving MUC information more reliable.
