The unstable modes of surface waves propagating in a sharply bounded turbulent plasma containing streaming ions are investigated by employing the specular reflection condition and the transverse truncation method. We have found that the bounded turbulent plasma supports damping and growing modes. The damping mode propagates for all values of the ion streaming speed modes and their behavior is similar to the case of surface waves in a turbulent plasma without ion streaming. If the speed of ion streaming is larger than the ion-acoustic speed, growing mode exists for all values of the wave number. However, if the ion stream is slower than the ion acoustic speed, then the growing mode appears under a certain condition. We derive the dispersion relations for such modes of surface waves and investigate the condition for propagation.

包含流动离子的湍流等离子体中不稳定的静电表面波：横向截断法

通过使用镜面反射条件和横向截断方法研究了在包含流动离子的边界急剧尖锐的湍流等离子体中传播的表面波的不稳定模式。我们发现有界湍流等离子体支持阻尼和增长模式。阻尼模式针对离子流速度模式的所有值传播，并且其行为类似于没有离子流的湍流等离子体中表面波的情况。如果离子流的速度大于离子声速，则对于波数的所有值都存在增长模式。但是，如果离子流慢于离子声速，则在特定条件下会出现生长模式。我们推导了这种表面波模式的色散关系，并研究了传播条件。
