摘要
本文讨论了文献［１］中介绍的用于分析时变网络的δ算法的截断误差和稳定性，并提出了一种变步长的改进算法。这种算法根据本次截断误差来调整下一个时间点上的步长，因而准确度高，稳定性好。
This paper analyses the truncated error and stability of the algorithm which hasbeen discussed in reference paper￣[1] and presents a modified algoritfrm in which the trun-cated error can be used to adjust the next step length so that it is more accurate and sta-ble.
