【Abstract】 We study the form invariance and Lie symmetry of a relativistic mec hanical system. Firstly, we give the definition and criterion and conserved quan tity of the form invariance and Lie symmetry in the system. Next, the relation b etween the form invariance and Lie symmetry of the system is obtained. Finally, we give an example to illustrate the application of the result.更多还原
