The rules of the cold-test characteristics changing with helix pitch are also studied and it turns out that, with increasing helix pitch, the phase velocity increases linearly, the interaction impedance changes nonlinearly and the attenuation constant decreases nonlinearly. At the same time, with the limitation of the synchronism between the electron beam and the electromagnetic wave, the change of pitch is small and therefore an approximate linear relation can be introduced.

研究表明：相速几乎随螺距增大而线性变大，互作用阻抗与螺距是非线性的关系，衰减常数随螺距增大而非线性地减小；由于在维持电子注与电磁波速度同步的限制下，螺距变化的幅度不可能很大，因此可近似按线性关系来处理互作用阻抗及衰减常数与螺距之间的关系。

因此，针对声源方向感受此一课题，以两反射音之模拟声场进行实验探讨，研究方法不仅以数理解析，并针对人们实验的心理感受进行调查分析，心理实验时采用配对比较法及恒常性图解法统计分析，试图藉由若干变因的控制进行量化，实验结果发现声源方向感度的变化，主要受制於双耳互函数级数及全反射音振幅的大小，双耳听觉互函数主要与反射到达测听者的方向和反射的幅度有关，证实声源方向感度与双耳互函数级数为正比之关系存在。

通过分析铜合金销与碳钢盘在干摩擦条件下相互对磨所产生的磨粒群和销试样磨损量，发现磨粒的累积分布和微分分布特性随磨损时间的变化而变化：在磨损开始阶段，磨损程度逐渐减小，磨粒群分布曲线由平缓变得逐渐凸、陡；达到磨损平衡状态后，磨损率达到最小，磨粒群微分布曲线的幅值达到最大，横向宽度达到最小；随着销与盘间互适性变弱，磨损程度增大，磨粒分布曲线变得越来越平缓，横向宽度逐渐增大；磨粒分布曲线随磨损时间的变化规律与磨损率随磨损时间的变化规律有明显的对应关系，可为科学诊断和预测摩擦学系统状态提供有用信息。

Theseall make the equivalent-potential model incorrect, which is a correct modelunder low frequency. Otherwise, the methods of segmentation are often used intransient computation. Many scholars ignored the effects of mutual-admittancebetween conductors when doing transient computation for the complexity.

另外，处理地网暂态往往采用分段的办法，如果考虑导体段之间的互导纳，将使计算变得复杂，因此很多学者计算地网暂态特性时往往没有考虑导体之间的互导纳。

作者用SPSS(10.0)数据处理系统分析了调查研究的结果并得出如下结论：一、总体上看，绝大部分学生认为学习成绩和努力之间有互变关系，同时把成功归咎于能力，从这点来说，学生们持有积极的归因信念。

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。
