Abstract：
Using the data sample accumulated with the Beijing Spectrometer at the center-of-mass energy of 4.03GeV,we have analysed τ^±τ^±→e^±+π^±+nπ⁰+ν's(n=0,1,2)events.The branching ratios are given as Br(τ^±→π^±ν_τ)=(11.64±0.49^+0.76_－0.73%,Br(τ^±→π^±π⁰ν_τ)=(24.00±1.34^+1.36_－1.30%,Br(τ^±→π^±2π⁰ν_τ)=(9.39±1.68^+1.69_－1.66%.
