摘要
该文研究了时间尺度上Nielsen方程的Mei对称性与守恒量.由链式法则建立时间尺度上单自由度的Nielsen运动微分方程;给出Nielsen方程的Mei对称性的定义和判据,得到守恒量;文末举例说明结果的应用.
Mei symmetries and conserved quantities of Nielsen equations on time scale are studied.Firstly,the Nielsen differential equations of motion with one degree of freedom on the time scale are established by the chain rule.Secondly,conserved quantities are derived from the definition and criterion of Mei symmetry of Nielsen equation.Finally,the application with examples is illustrated at the end of this paper.
