It also eliminates the invalid paths between statuses considering the restriction of minimum continuous time of on and off , and tamps rates , thereby reducing the number of paths in dynamic programming and attaining the aim of reducing dimensions . After confirming the running or suspended status of units , the approach is used to distribute powers among units , thereby increasing the efficiency of dynamic programming greatly .

通过比较各时段负荷及机组参数，剔除各时段下不满足要求的组合状态，从而减少动态规划中的状态点数；根据机组的最小连续运行，停运时间限制，计及机组功率上升，下降速度的约束，剔除了状态点间的无效路径，从而减少了动态规划的路径个数，达到降维的目的；在确定机组启停状态后，再采用解析法进行机组的功率分配，可以大大提高动态规划方法的效率。

The results show that:(1) The space-charge fields(include dc space-charge fields and ac space-charge fields) have important effect on the beam-wave interaction output power, make the saturated output power lower, saturated position delay;(2) The back-radio excited by the electron beam has little effect on the output power, and can be ignored;(3) The transverse motions of electron beam has some effect of the output power;(4) The means of phase velocity taped and bunch compression can improve the relativistic TWT efficiency, especially bunch compression can greatly improve the efficiency.

五、分析了相对论行波管三维非线性特性，分析结果表明：(1)空间电荷场（包含直流和交流空间电荷场）对注波互作用输出功率影响很大，会造成饱和输出功率减小，饱和位置推后；(2)电子注激发的反向辐射对输出功率影响比较小，基本上可以忽略不计；(3)电子注横向运行对注波互作用的直接影响比较大；(4)通过改变耦合腔内半径来调节慢波结构相速，采用相速跳变和预群聚的方法可以改善相对论行波管的效率，特别是采用预群聚方法，可以尽量提高相对论行波管的效率。
