A reduction of the two-time formalism [V. I. Erofeev, Journal of Plasma Physics 85, 905850104 (2019)] to a highly informative scenario of redistribution of plasma particles in momentum due to Coulomb collisions is reported. The standard case of an ideal classical ionized homogeneous plasma is considered. It is found that the leading-order approximation of the scenario is consistent with the well-known Lenard–Balescu Equation [A. Lenard, Ann. Phys. 10, 390–400 (1960); R. Balescu, Phys. Fluids 3, 52–63 (1960)]. A correction to the collision integral of this equation is developed to account for the time variation of plasma parameters. This correction is shown to differ from its analogs related to the existing generalizations of the Lenard–Balescu kinetic equation [Yu.L. Klimontovich, Kinetic theory of nonideal gases and nonideal plasmas (Pergamon Press, Oxford [1982]); V.V. Belyi, Yu.A. Kukharenko, J. Wallenborn, Journal of plasma physics 59, 657–669 (1998)].

等离子体演化对等离子体碰撞弛豫动力学场景的影响

据报道，将两次形式主义 [VI Erofeev, Journal of Plasma Physics 85 , 905850104 (2019)] 简化为库仑碰撞导致等离子体粒子在动量中重新分布的信息量很大的场景。考虑理想经典电离均质等离子体的标准情况。发现该场景的前导近似与著名的 Lenard-Balescu 方程 [A. 莱纳德，安。物理。10 , 390–400 (1960); R. Balescu，物理。流体3, 52–63 (1960)]。对这个方程的碰撞积分进行了修正，以解释等离子体参数的时间变化。这种修正显示出不同于与现有的 Lenard-Balescu 动力学方程的概括相关的类似物 [Yu.L. Klimontovich，非理想气体和非理想等离子体的动力学理论（佩加蒙出版社，牛津 [1982]）；VV Belyi, Yu.A. Kukharenko, J. Wallenborn, 等离子体物理学杂志59 , 657–669 (1998)]。
