Abstract：By analogy to Lyapunov function, whether or not an appropriate Lyapunov function can be constructed is the key to the study of the stability of nonlinear timedelay system. A class of fourthorder differential equation is studied. By constructing sufficient conditions of the asymptotic stability of zero solution of equation, the adequate criteria of the asymptotic stability of zero solution of equation is obtained.
