研究了完整力学系统Tzénoff方程Mei对称性直接导致的另一种守恒量,给出了这种守恒量的函数表达式和导致这种守恒量的确定方程.利用该方法比以往更易找到守恒量.最后举例说明了新结果的应用.
Another kind of conserved quantity deduced from Mei symmetry of Tzénoff equations for holonomic systems is studied. The expression of this conserved quantity and the determining equation to induce this conserved quantity are presented. The results indicate that this new method is easier to find conserved quantities than methods reported previously. Finally, application of this new result is presented by a practical example.
