Abstract：
The reconstruction method of muon tracks in the L3 Cosmic Ray Experiment has been studied.The affection caused by the non-uniformity of magnetic field,multiple scattering and other random processes have been investigated by the Geane package.After correction,the momentum resolution of the reconstructed muons was improved.
