Abstract：
An algorithm to construct the generator of gauge transformation for a constrained Hamiltonian system is given.The relationships among the coefficients connecting with first-class constraints in the generator is cleared.Based on the phase space generating functional,the corresponding Ward identities in canonical formalism is deduced.The preliminary applications of above results to a model in field theory which is functionally equivalent to the mixed Chern-Simons Lagrangian is discussed in detail.
