英文摘要	The error matrix correction for charged track parameters of BES II detector is carefully studied. The proper MDC wire spatial resolution (sigma = 250 mum) and Q correction are incorporated into BES II data reconstruction program. The BES II effective material passed through by tracks from interaction point to MDC is taken into account in the kinematics fitting package TELESIS,to correct the multiple scattering and dE/dX energy loss effects. By analyzing the J/psi --> mu (+)mu (-) data sample,the RUN-by-RUN error matrix calibration is completed for BES Il 24 X 10(6) J/psi events. After these corrections of the error matrix,TELESIS can be applied to BES II J/psi data analysis with fairly good accuracy.
