研究了有限振幅弱色散圆极化磁流体波列在斜调制下的稳定性。该数学模型是DNLS方程的多维扩展。我们已经发现，右手偏振波，这是稳定的平行调制，是不稳定的，相对于某些倾斜调制的大多数主要波数。
The stability of finite-amplitude weakly dispersive circularly polarized MHD wave trains with respect to oblique modulations is investigated. The mathematical model is a multi-dimensional extension of the DNLS equation. We have found that the right-hand-polarized wave, which is stable with respect to parallel modulations, is unstable with respect to certain oblique modulations for most primary wavenumbers.
