We state some widely satisfied hypotheses, depending only on two functions $g$ and $h$, under which the composition of a stable algorithm for $g$ and a stable algorithm for $h$ is a stable algorithm for the composition $g \circ h$.

翻译：我们提出一些普遍满意的假设,仅取决于两个功能:一是g美元,二是h美元。 根据这两个功能,美元的稳定算法和美元的稳定算法的组成,是构成g /circ h美元的稳定算法。
