摘要: 本文以二阶齐次常微分方程的Numerov格式为出发点,构造了二阶积分-微分方程和二阶积分-微分方程组的迭代求解格式,比直接解法(高斯全主元消去法)不但大大节约了计算机的存贮量,而且也大大节约了计算时间。

Abstract: In this paper, Numerov iterative method for second order integral-diffe-rential equation arid system of-equations are constructed. Numerical examples show that this method is better than direct method (Gauss elimination method) in CPU time and memery require. Therefore,this method is an efficient method for solution of integral-differential-equation in nuclear physics.
