本文件的目的是统一空间物理不同领域中使用的各种湍流波传输方程。在这里，我们主要关注磁流体湍流，特别是Alfvénic湍流。然而，所应用的方法是通用的，并且可以扩展到其他形式的湍流，例如声学湍流或朗缪尔等离子体波。只要稍加修改，下面的推导就可以扩展到相对论运动，从而可以将它们应用于具有高等离子体速度(无线电喷射)或强重力(黑洞周围)的天体中的波传输。
The aim of the present paper is to unify the various transport equations for turbulent waves that are used in different areas of space physics. Here, we mostly focus on the magnetohydrodynamic turbulence, in particular the Alfvénic turbulence. The applied methods, however, are general and can be extended to other forms of turbulence, for example the acoustic turbulence, or Langmuir plasma waves. With minor modifications, the derivations followed here can be extended for relativistic motions, thus making it possible to apply them to the wave transport in astrophysical objects with high plasma speeds (radiojets), or strong gravity (black hole surroundings).
