研究等离子体振荡静电谐波的广义弱湍流理论[P]。H. Yoon，物理学家等离子体7,4858(2000)]不包括自发热波动引起的影响。本文通过将讨论扩展到包括单个粒子效应来弥补这一缺陷。从目前的分析中出现的形式不仅描述了各种自发的标准波粒相互作用，而且还可以用来确定静电谐波的初始水平，这是以前的理论所缺少的一个关键特征，必须以一种特殊的方式处理。
Generalized weak turbulence theory which deals with the electrostatic harmonics of plasma oscillation [P. H. Yoon, Phys. Plasmas 7, 4858 (2000)] does not incorporate the effects arising from spontaneous thermal fluctuations. This paper remedies such a shortcoming by extending the discussion to include individual particle effects. The formalism which emerges from the present analysis not only depicts various spontaneous wave-particle interactions of the standard variety, but it can also be used to determine the initial levels of the electrostatic harmonics, a crucial feature which was missing from the previous theory and which had to be dealt with in an ad hoc manner.
