| 摘 要： | 文中实验研究证实了BGK模离子声波的存在.用连续波和调制脉冲波两种方法研究了由慢电子漂移引起的增长离子声波不稳定性.同时首次测量了激发BGK模离子声波的条件.得到的结果与理论预言是一致的.

| Abstract: | The existence of BGKmode's Ion Acoustic Wave (IAW) is verified experimentally. The growing ion acoustic wave instability caused by the slow electron drift is studied by both CWand pulse modulated wave methods.The optimum conditions for exciting BGKmode's IAWare obtained experimentally in an unmagnetized plasma for the first time. The results are quite agreeable with the theoretical preduction. |
