本文在电子注射理论的基础上,进一步考虑到在高电埸的作用下,介质内电子有离开价带,跃迁到导带的现象,提出了埸致电极和埸致介质发射综合效应所导致的树枝引发机理,推出了聚乙烯树枝引发的V—t特性,并得到实验证明,最后,还讨论了有关的实验现象。 Based on the theory of electron injection, we further consider the phenomenon that electrons in the medium leave the valence band and transition to the conduction band under the action of high electric field, and bring forward the effect of the combined effect of the induced electrode and the induced medium The mechanism of branch initiation is introduced, and the V-t characteristic induced by polyethylene branch is introduced and proved experimentally. Finally, the related experimental phenomena are also discussed.
