Abstract: In this paper, we adopt the theory of continuation structure and properties of simple or semi-simple Lie algebra and studied the prolongation structure for two dual systems. Furthermore, the Lax pair of these equations are obtained by the method of Lie representation theory. Considering the CH type equation, based on analysing its determined equations, we select the functions F that ord(F) ≤ 2. However, there merely exists one order situation through calculation and analysis.

Key words: Generalized coupled equation, Prolongation structure, Dual system, Lax pair
