摘要
研究二阶非Четаев型完整系统的守恒律· 引入Jourdain生成元 ,给出无限小变换下Jour dain原理的不变性条件 ,在一定条件下得到系统的守恒律· 并举例说明结果的应用·
The conservation law of second_order nonholonomic system of non_chetaev's type by means of the Jourdain's principle was studied. The invariant condition of Jourdain's principle under infinitesimal transformation is given by introducing Jourdain's generators. Then the conservation law of the system is obtained under certain conditions. Finally a calculating example is given.
