Abstract : in this paper, the authors study the initial value problems of a class of weakly nonlinear differential equation. the first and the second order approximate solutions are obtained. their accuracies are high and the more the approximate order is high, the more the accuracy is high. if the regular perturbation method is used to solve the same problems, then, when the independent variable is big, so is the error of the solution
文摘:用插值攝動法1研究一類弱非線性常微分方程的初值問題，得到了一級及二級近似解.解的精度很高，並逐級提高.如果用正則攝動法求解此類問題，則當自變量較大時，誤差很大
