【正】 In this paper,the form invariance and the Lie symmetry of Lagrange’s equations for nonconservativesystem in generalized classical mechanics under the infinitesimal transformations of group are studied,and the Noether’sconserved quantity,the new form conserved quantity,and the Hojman’s conserved quantity of system are derived fromthem.Finally,an example is given to illustrate the application of the result.
