摘    要:验证了一种常微分方程数值解整体截断误差估计方法,它主要利用不同阶数的自适应RK方法对问题进行求解;证明了精度较高的RK方法的整体截断误差可以作为原问题的整体截断误差,该方法具有与原方法同数量级的时间复杂度。并对弹簧振子问题进行了验证,还据此对三体问题进行了计算。

关 键 词:常微分方程数值解  整体截断误差  Rouge-Kutta-Felberg方法  三体问题

Abstract:The paper examines a method of evaluating the overall truncation error for numerical solutions to ordinary differential equations. This method uses different order Rouge-Kutta method to get the accuracy of the solutions,with the same magnitude of time complexity of the original method, and calculates three-body problem with it.
Keywords:numerical solutions of ordinary differential equations  total absolute error  Rouge-Kutta-Felbery method  three-body problem
