                                 Abstract:The identification of tau one prong hadronic decay using neural network is presented.Based on the identification,we measured the branching ratios: Br(π/Kv)=(12.18±0.26±0.42)%,Br(π/Kπ0v)=(25.20±0.35±0.50)%,Br(π/K2π0v)=(8.88±0.37±0.38)%,Br(π/K3π0v)=(1.70±0.24±0.39)%.
