针对沿着磁场传播的波，求解了离子 Weibel 不稳定性的拟线性方程。估计激发波的能量，并确定饱和阶段离子分布函数的矩，作为地球磁尾中性片特征参数的当前速度的函数。研究的问题是亚暴爆发阶段开始时的当前中断是否可以解释为由于离子韦贝尔不稳定性的开始。
The quasilinear equation for the ion Weibel instability is solved for waves propagating along the magnetic field. The energy of the excited waves is estimated and the moments of the ion distribution function in the saturation stage are determined as functions of the current velocity for parameters characteristic of the neutral sheet of the Earth's magnetotail. The question is studied of whether the current disruption at the beginning of the explosive phase of a substorm can be explained as being due to the onset of the ion Weibel instability.
