在弱湍流理论的框架下，研究了横向电流作用下等离子体中离子回旋不稳定性的饱和，当电流速度小于离子热速度时。结果表明，饱和主要是由自由离子对回旋振荡的非线性散射引起的，而波的衰减、电子波的诱导散射和虚波的离子极化云的诱导散射则不重要。估计了与第一过程有关的稳态湍流水平和电子的湍流加热速率。
The saturation of the ion cyclotron instability of a plasma with a transverse current is studied in frame of the weak turbulence theory for the case when the current velocity is less than the thermal velocity of ions. It is shown that the saturation is mainly due to a nonlinear scattering of cyclotron oscillations by free ions whereas decay of waves, induced scattering of waves from electron and induced scattering from ion polarization clouds of virtual wave are of no importance. Steady state turbulence level related to the first process and the rate of turbulent heating of electrons are estimated.
