变质量非完整系统的Lagrange对称性与守恒量
Symmetry and conserved quantity of Lagrangians for nonholonomic variable mass system
摘要
Abstract
In this paper are study the symmetry of Lagrangians and the conserved quantities for a nonholonomic variable mass system. Firstly,the criterion of the symmetry of Lagrangians for a nonholonomic variable mass system is given.Secondly,the conditions under which there exist a conserved quantity and the form of the conserved quantity,are obtained.Finally,an example is given to illustrate the application of the results.关键词
