Abstract：
Based on the experimental data of the cross section e⁺e^－→π⁺π^－π⁺π^－ measured by the BABAR collaboration, we apply the theoretical cross section deduced from the extended VMD (Vector Meson Dominance) model to fit these experimental results. It is the first time that the isovector form factor and the relevant parameters are obtained through one decay mode.
