摘　　要：研究非保守力学系统Nielsen方程的形式不变性 .给出非保守力学系统Nielsen方程的形式不变性的定义和判据 ,研究形式不变性和Noether对称性的关系 。A form invariance of Nielsen equation of nonconservative mechanical system is studied. The definition and criterion of the form invariance of Nielsen equation of a nonconservative mechanical system are given. The relation between the form invariance and the Noether symmetry is studied. Some examples are given to illustrate the application of the result.
