【Abstract】 The variational equations are established for holonomic nonconservative dynamical systems in the high-dimensional ex-tended phase space.The canonical equations of systems and their variational equations are used to prove that an integral invariant can be directly constructed by the first integral of the systems.Finally one example is given.更多还原
