Abstract： The structure functions in the τ→3πv decay are extracted using the model proposed by Li. The predictions of Li model are compared with KS ones and the data from OPAL experiment. It is found that predictions by the model for ωA (Q2) are consistent with the data except for in the high energy region (Q2 > 1.2 GeV2 ) , and ωC, ωD, ωE normalized to ωA are in reasonable agreement with the experimental results. Correction factors to the Breit-Wigner distribution of a1 and the Lagrangian of this decay are proposed to the model.
