研究了三个非线性耦合漂移波的相互作用，以了解相位随机化的发生以及随机相位近似的适用性。漂移波非线性包括对于适当的垂直波数值线性不稳定的波的 E×B 和偏振漂移耦合。给出了精确三波相互作用的守恒性质和样本数值解以及相应的随机相位近似方程的守恒性质和解。
The interaction of three nonlinearly coupled drift waves is investigated for the occurrence of stochastization of the phases and the applicability of the random phase approximation. The drift wave nonlinearities include the E×B and polarization drift couplings for waves that are linearly unstable for appropriate values of the perpendicular wavenumber. The conservation properties and sample numerical solutions for the exact three wave interaction are given along with the conservation properties and solutions of the corresponding random phase approximation equations.
