| 摘 要： | Mei symmetry and Mei conserved quantity for a non-holonomic system of non-Chetaev＇s type with unilateral constraints in the Nielsen style are studied. The differential equations of motion for the system above are established. The definition and the criteria of Mei symmetry, conditions, and expressions of Mei conserved quantity deduced directly from the Mei symmetry are given. An example is given to illustrate the application of the results.
