    用改进的L-P法求解了强非线性Duffing方程和一类非振动型强非线性微分方程的初值问题，计算过程简单，精度也比张佑启等[2]的改进的L-P法的更好.

    In this paper, using the improved L-P method, the author seeks to solve the initial value problems of the strongly nonlinear Duffing equation and a class of nonoscillation type differential equation. Its calcultation process is quite simple and the accuracy of the results of this paper is better than that of the improved L-P method proposed by ZHANG Y. Q[2].
