摘　　要：The Hellmann-Feynman （H-F） theorem is generalized from stationary state to dynamical state. The generalized H-F theorem promotes molecular dynamics to go beyond adiabatic approximation and clears confusion in the Ehrenfest dynamics.The Hellmann-Feynman （H-F） theorem is generalized from stationary state to dynamical state.
