Abstract：
Two methods are used to improve the L3 TEC resolution at track vertex.First,refit the lepton tracks by constrained curvature from high precision measurements on electron energy and muon momenta. Second, correct the average value of track offsets in each half sector of TEC.Combined methods improve the lepton track resolution at vertex from 137μm to 60μm.
