Abstract：
Starting from phase-space generating functional for the system with regular and singular Lagrangian respectively,the canonical Ward identities under the global symmetry transformation in phase space are deduced.The corresponding local transiormation is studied,the conserved charge is obtained at quantum level and the canonical Noether theorem in quantum case is given.The preliminary application of the results to a system of interacting nucleons and pious is discussed.
