摘　　要：讨论了存在相关约束的Euler Lagrange方程解的存在唯一性条件,给出了一个存在唯一性定理。定理中不再要求Φx满秩,从而推广了以前的结论。文中还讨论了定理的应用背景。EulerLagrange equation system is one of the most important mathematical models in analytic mechanics and multibody system dynamics. There often exist dependent constraints in the equations of the systems such as parallel mechanisms. The existence and uniqueness of the solution for such systems has not been discussed, a theorem is given on this problem, which is an extension of previous results.
