The stability of singular points of two degree of freedom autonomous Lagrange system is studied. Firstly,the differential equations of two degree of freedom autonomous Lagrange system are given; then,the singular points equations of this system are obtained and the Lyapunov indirect method is extended to the system; finally,the method of judging the stability of singular points of this system is obtained and an example is given to illustrate the application of the results.
