摘　　要：In this paper,the Mei symmetry of Tzénoff equations for the higher-order nonholonomic system and the new conserved quantities derived from that are researched,and the function expression of new conserved quantities and criterion equation which deduces these conserved quantities are presented.This result establishes the theory basis for further researches on conservation laws of Tzénoff equations of the higher-order nonholonomic constraint system.In this paper, the Mei symmetry of Tz6noff equations for the higher order nonholonomic system and the new conserved quantities derived from that are researched, and the function expression of new conserved quantities and criterion equation which deduces these conserved quantities are presented. This result establishes the theory basis for further researches on conservation laws of Tz6noff equations of the higher - order nonholonomic constraint system.
