摘要：
By introducing the generalized quasi-symmetry of the infinitesimal transformation fortransformation group G,,this paper studies the conservation laws and symmetries of dynamical systemswith unilateral constraints in phase space.Noether’s theorem and Noether’s inverse theorem for me-chanical systems with unilateral constraints in phase space are obtained and two kinds of equivalentforms of generalized Killing equations which are used to determine the 8enerators of the infinitesimalgroup transformation are given.
