It shows that it is possible to increase the start oscillation length by tailoring magnetic field's amplitude and its period without changing the synchronous condition of the fundamental wave; in the meantime, when there are two or more azimuthally asymmetric space harmonics in the high power broad-band helix TWTtraveling wave tu...

与此同时，对起振长度、初始非同步速度参量随皮尔斯增益参量、空间电荷参量、损耗参量等的变化，以及在超宽带行波管中当存在两个或多个角向非对称空间谐波时，起振长度、初始非同步速度参量随周期永久聚焦磁场的变化进行了研究。优化设计聚焦磁场、电子注和螺旋线慢波系统的参量可以对螺旋线行波管的稳定性分析提供必要的依据。

The experiment and theory proved that the wear resistance and fatigue resistance of the ductile iron crankshaft could be greatly improved,and also the uniform layer of hardness and residual stress could be obtained by the second method-the laser circumference continuously scans the neck of crankshaft,and the laser forms 45°angle with the central line of crankshaft to scan the partial filleted angle of the crankshaft.
