摘　　要：构造了含Chern Simons(CS)项的旋量电动力学的规范变换生成元 .按约束Hamilton系统的Faddeev Senjanovic(FS)路径积分量子化方案 ,给出了该系统Green函数的相空间生成泛函 ;导出了正则Ward恒等式 ;分析了系统的量子守恒角动量 。The generator of gauge transformation for spinor QED with Chern-Simons (CS) term has been constructed. According to the rule of path integral quantization for constrained system in Faddeev-Senjanovic scheme, the phase-space generating of Green function is obtained, and canonical Ward identities for such a system is also derived. The quantal conserved angular momentum for spinor QED with CS term is studied. The property of fractional spin of the system is pointed out.
