Abstract：
The Michel parameter ρ_τ→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.
