摘　　要：对单面完整约束系统在相空间中的形式不变性进行了分析研究。给出了单面完整约束系统在相空间中形式不变性的定义和判据 ,得到了形式不变性的结构方程和守恒量 ,并用实际算例验证了研究结果的有效性。The form invariance of holonomic systems with unilateral constraints in phase space was studied. The definition and the criterion for the form invariance of holonomic systems with unilateral constraints in phase space were given. The structure equation and the conservation law for the form invariance were obtained. The example demonstrated the validity of the researched result.
