本文介绍了电磁电子回旋不稳定性轴向和角向群聚机理的比较研究。轴向群聚可用非相对论处理来说明,而角向群聚其起因是相对论性的。众所周知,轴向群聚机理激励起韦伯型(Weibel-type)不稳定性,而角向群聚机理则激励电子回旋脉泽的不稳定性。对于冷螺旋轨道的电子群,本文给出了两种不稳定性统一的

This paper presents a comparative study of the mechanism of axial and angular congruency of the electromagnetic cyclotron instability. Axial clustering can be used to illustrate the non-relativistic treatment, and the causes of angular clustering is relativistic. It is well-known that the axial clustering mechanism excites Weibel-type instability, whereas the angular clustering mechanism excites the instability of the electron mantle. For the electron cluster of a cold helical orbit, this paper gives two unification instabilities
