研究了数值求解延时微分方程的步长准则.据此,提出了延时微分方程具有刚性的概念.最后以一个数值例子分析了求解刚性延时微分方程的困难性.
研究瞭數值求解延時微分方程的步長準則.據此,提齣瞭延時微分方程具有剛性的概唸.最後以一箇數值例子分析瞭求解剛性延時微分方程的睏難性.

We study the step criteria of numerical methods for delay differential equations. Based on thecriteria, we define the concept of stiffness of a class of delay differential equations. We also give anumerical example which illustrates the difficulty for solving stiff delay differential equations with large raterD.
