摘　　要：利用 Nambu-Jona-Lasinio( NJL)机制 ,由不包含 Fayet-Iliopoulos( F-I)项的超规范Wess-Zumino模型出发 ,计算并给出了由费米场和规范场的自能所决定的标量场的非零真空期待值 。In terms of the Nambu Jona Lasinio(NJL)mechanism, starting from the supergauge Wess Zumino model, the non vanishing vacuum expectation value of the scalar field has been calculated, from which one can see that the vacuum expectation value is determined by the self energy of the fermions and the gauge bosons, and then it is proved that the supergauge symmetry can be broken down by dynamical mechanism.
