摘　　要：高频离子声波由于Landau阻尼很大,一般难以激发。本文研究了表面约束稳态装置上高频离子声波的激发特性。实验表明,仔细控制放电参数可以激发起纯离子声波,密度涨落n/n_o最大可以达到7.5％。It is difficult to launch high frequency ion acoustic waves in a Maxwellian plasma due to the large Landau damping. In this paper, the launching characteristics of high frequency ion acoustic waves in a stable surface confinement plasma device are studied. The experimental results show that pure acoustic waves can be launched by controlling the discharge condition carefully and the density fluctuation n/n_0 in plasma is 7.5% at maximum.
