摘　　要：本文对四阶Adams-Bashforth-Moulton(ABM)预测-校正算法进行改进,获得了带修正值的四阶ABM预测-校正算法;通过数值算例运用MATLAB语言对它们的计算结果与精确解的误差进行比较。结果表明:带修正值的四阶ABM预测-校正算法的误差更小,有一定的应用价值。Based on improving the four order Adams-Bashforth-Moulton （shorten as methods, we got the modifier formula of the ABM methods. Using Matlab language, we ABM） predictor-corrector compared the solutions of those methods with the exact solution of a numeric example. The results said the error of the modifier formula of the four order ABM predictor-corrector is smaller than that of the the four order ABM predictor-corrector.
