研究了有限振幅左旋圆极化Alfvén波在考虑二阶密度扰动和磁场扰动时的不稳定性。找到了成丝发生的最小尺度长度和时间。我们的结果应用于应该在星际介质（ISM）中散射宇宙线的阿尔文波。
The filamentation instability of finite amplitude left-hand circularly polarized Alfvén waves has been investigated taking into account the second-order density and magnetic field perturbations that are created by the Alfvén wave pressure. The minimum scale length and time over which the filamentation occurs, are found. Our results are applied to Alfvén waves that should scatter cosmic rays in the interstellar medium (ISM).
