研究了完整力学系统Tzénoff方程的三种对称性及其直接导致的守恒量,给出了导致这些守恒量的判据方程和守恒量的函数表达式,最后举例说明了研究结果的应用
Three conserved quantities are deduced from symmetries of Tzénoff equations for holonomic systems. The determining equations to induce these conserved quantities are given, and the expressions of them are presented. Finally, applications of the research result are illustrated by practical examples.
