At the same time, the general form of generators of one-parameter Lie group which is accepted by two particular classes of second order automatic systems is given, thus the integrating factor of the system is constructed. (2) Base on Lie group theory, the method to obtain the integrating factors of the third order autonomous system by using of two one-parameter Lie groups accepted by the system is given and shown.
