| Abstract: | In this paper, on the basis of the improved L Pmethod, replenishing to consider the variarue of the amplitude of uabration, the authors obtain a first order approximate solution of a class of problems of the positively damped strongly nonlinear free oscillations. This solution has good accuracy. |
