提出了电流驱动离子声不稳定性饱和的非线性理论。饱和机制是通过有限幅度波改变离子轨道,从而导致离子捕获。结果与 Biskamp 和 Chodura 最近的计算机模拟以及 Hamberger 和 Jancarik 的实验进行了定量比较。
A nonlinear theory is presented for the saturation of the current-driven ion-acoustic instability. The saturation mechanism is the modification of ion orbits by finite-amplitude waves, leading to ion trapping. The results are quantitatively compared with recent computer simulations of Biskamp and Chodura, and experiments of Hamberger and Jancarik.
