摘要
本文考虑变系数变延迟微分方程在任意步长的单腿θ—方法的数值有界稳定性,给出了单腿θ-方法稳定的充分必要条件．即考虑任意步长hn情况下单腿θ-方法的数值有界稳定性,分别得到与固定步长情况下数值有界稳定充分必要条件相同的结果．
In this paper, we investigated the Bounded Stability analysis of the single legθ- methods for variable cofficient and variable delay of delay differential equations, applied a variable step ofθ- metheds obtaining the sufficient and necessary conditions of numerical stability for the single legθ- methods.
