| Abstract: | This paper is intended to study a new conserved quantity as a direct result of the Mei symmetry for non-holonomic systems.The expression of such a new conserved quantity and its condition equation are presented here.It is easier to find out conserved quantities than ever by using above method.An example is showed to explain the application of the new results. |
