A previous paper [P. H. Yoon，“重新审视平行传播的湍流动力学理论：正式结果，”Phys. Plasmas 22，082309（2015）]重新审视了在与环境磁场平行/反平行的方向上传播的湍流的二阶非线性动力学理论，其中根据Yoon和Fang的原始工作[Phys. Plasmas 15，122312（2008）]被细化，根据Gaelzer等人的论文[Phys. Plasmas 22，032310（2015）]。主要发现涉及的尺寸修正有关的离散粒子的影响，尹和方的理论。然而，最终的结果是在正式的线性和非线性磁化率响应函数。本文利用响应函数的近似形式，给出了中低频区的形式方程。由此产生的方程是足够具体的，使他们可以很容易地解决数值方法或分析的理论…
A previous paper [P. H. Yoon, “Kinetic theory of turbulence for parallel propagation revisited: Formal results,” Phys. Plasmas 22, 082309 (2015)] revisited the second-order nonlinear kinetic theory for turbulence propagating in directions parallel/anti-parallel to the ambient magnetic field, in which the original work according to Yoon and Fang [Phys. Plasmas 15, 122312 (2008)] was refined, following the paper by Gaelzer et al. [Phys. Plasmas 22, 032310 (2015)]. The main finding involved the dimensional correction pertaining to discrete-particle effects in Yoon and Fang's theory. However, the final result was presented in terms of formal linear and nonlinear susceptibility response functions. In the present paper, the formal equations are explicitly written down for the case of low-to-intermediate frequency regime by making use of approximate forms for the response functions. The resulting equations are sufficiently concrete so that they can readily be solved by numerical means or analyzed by theoretical ...
