摘      要：The structure functions in theτ→3πv decay are extracted using the model proposed by *** predictions of Li model are compared with KS ones and the data from OPAL *** is found that predictions by the model forωA(Q2)are consistent with the data except for in the high energy region(Q21.2 GeV2),andωC,ωD,ωE normalized toωA are in reasonable agreement with the experimental *** factors to the Breit-Wigner distribution of a1 and the Lagrangian of this decay are proposed to the model.
