Abstract: In this paper,using the improved L-P method,the a ut hor seeks to solve the initial value problems of the strongly nonlinear Duffing equation and a class of nonoscillation type differential equation.Its calcultati o n process is quite simple and the accuracy of the results of this paper is bette r than that of the improved L-P method proposed by ZHANG Y.Q.

Key words: singular perturbation, improved, L-P method, strongly no nlinear, duffing equation
