发生在等离子体中的弱湍流过程通常用动力学理论来表述。然而，由于这个问题固有的复杂性，到目前为止，这个理论主要是针对非磁化等离子体发展起来的。本文证明了热双流体理论可以成功地部分表述空间均匀等离子体中的弱湍流理论。具体地说，证明了非线性波-波相互作用或衰减过程可以用双流体形式再现。目前的发现表明，同样的方法原则上可以扩展到磁化等离子体，这是未来工作的主题。
Weakly turbulent processes that take place in plasmas are customarily formulated in terms of kinetic theory. However, owing to an inherent complexity associated with the problem, thus far the theory is fully developed largely for unmagnetized plasmas. In the present paper it is shown that a warm two fluid theory can successfully be employed in order to partially formulate the weak turbulence theory in spatially uniform plasma. Specifically, it is shown that the nonlinear wave-wave interaction, or decay processes, can be reproduced by the two-fluid formalism. The present finding shows that the same approach can in principle be extended to magnetized plasmas, which is a subject of future work.
