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。

The theoretical analysis shows the decouple of rotation and levitation. The rotor is actively controlled only in two radial directions and rotation while the other three motions are passively stable owing to the short-span structure.

理论研究表明这种结构的无轴承电机的磁悬浮径向力和电机的转矩是相互解耦的，又因为它是片状永磁转子结构，只须控制转子的两个径向自由度和旋转自由度，其他三个自由度是被动稳定的。

Even yesterday, he did a full run-through of his long program when everyone else was kind of just walking through the motions.

他甚至在昨天比赛前的训练里还完成了全套的自由滑，而其他人都只是走走过场而已。

The resulting standing wave is a swirling motions such as might result if we swirled water in a round-bottomed cup.

所产生的驻波是一种旋转运动，它是在我们转动圆底杯中的水时会产生的现象。

In this text we will explore the topics of kinematics and dynamics of machinery in respect to the synthesis of mechanisms in order to accomplish desired motions or tasks, and also the analysis of mechanisms in order to determine their rigid-body dynamic behavior.

1.0 目的在这文本里我们将探索动力学题目并且机械动力学关于机制综合为了完成渴望行动或任务，和对机制的分析为了并且确定他们的刚性身体动态行为。

The simple use of the pump fake and the effortless use of the pivot foot leave the defender lost in a fury of motions.

简单地运用虚晃，再加上轻松地控制轴心脚，这便让防守者在一连串动作中眼花缭乱。

So when I was around 14 and my younger sister wanted to get her ears pierced, I had a moment of stunning clarity, like one of those kung fu slow motions in a Crouching Tiger film, where I realized that drilling a hole in your ear lobe is just…well…odd.

所以当我大约14岁时，我的小妹想要穿耳洞，我有片刻惊人的清醒，就像是在一部&卧虎藏龙&电影中的其中一个功夫慢动作，我意识到在你的耳朵上挖一个洞只是有些。。。是的。。。奇怪的。
