Abstract: The Michel parameter ρτ→e is determined through studying the electron energy spectrum of τ→eνν decay by Beijing Spectrometer(BES). This paper describes the electron identification with dE/ dx、β、E/p informations for charged particles and their, adequate combinations using e+e collision data collected at s=4.03GeV.
