Abstract
A kind of symmetries,i.e.a weakly Noether symmetry for a Lagrange system is presented.The criterion of the weakly Noether symmetry of the system is given and a Noether conserved quantity can be deduced using the symmetry.The weakly Noether symmetry finds more applications than the Noether symmetry.
