The dynamic behavior of large amplitude ion-acoustic double layers in a plasma is investigated in the presence of two-temperature nonextensive electrons. The effects of physical parameters, such as the temperature and concentration of positive ions on the formation and structure of double layer are discussed. It is shown that the depth of the Sagdeev potential and the amplitude of both positive and negative ion-acoustic double layers sensitively depend on the temperature and the concentration of positive ions. The obtained results are also compared with the results of a similar Maxwellian plasma with warm ions and two (cold and hot) electron species.

两温不扩散电子对离子声双层的影响

在存在两个温度的非扩展电子的情况下,研究了等离子体中大振幅离子声双层的动态行为。讨论了物理参数(如温度和正离子浓度)对双层形成和结构的影响。结果表明,Sagdeev电位的深度以及正负离子声双层的振幅都敏感地取决于温度和正离子浓度。还将获得的结果与具有温离子和两个(冷和热)电子物种的类似麦克斯韦等离子体的结果进行比较。
