Abstract: Using “analogy method”  is used to discuss the constructure of  Lyapunuov function,a class of nonlinear system.A sufficient condition is obtained for the stability of the ordinary solution to the three-nonlinear fourth order system.

Key words: nonlinear system, Lyapunuov functions, stability, sufficient conditions
