本文采用空间电荷波的观念,讨论了包括电子相互作用的多次聚束问题。所得结果,在电流接近以零为极限时,简化成费恩柏格(E.Feenberg)由运动学观点出发的结果。但是空间电荷效应的包括,显示了多次聚束系统一些不能由运动学方法得到的特徵。本文的分析,可以应用在一系列的微波电子器件上。文中对这方面,也提供了一些具体的方向。In the present work, a theory of multiple bunching including the effect of space-charge is developed through the use of space-charge wave concept. The results contain Feenberg's kinematic theory as a special case and reveal characteristics of multiple bunching system that could not be obtained from the kinematic approach.The theory will find applications in microwave electronic devices and some examples of practical significance are discussed.
