摘要

本论文探讨了一个未决问题，即如何根据麦克斯韦方程组全集推导速度达到光速并产生电磁场的带电粒子系统的相对论弗拉索夫方程。此外，还说明了非相对论动力学模型的推导方法。还演示了相对论流体力学的独立推导。这些流体力学和动力学方程推导的关键作用包括库兹缅科夫（L.S. Kuzmenkov）提出的在物理无限小体积上平均化的明确算子。

Hydrodynamic and kinetic representation of the microscopic classic dynamics at the transition on the macroscopic scale

An open problem of the derivation of the relativistic Vlasov equation for systems of charged particles moving with velocities up to the speed of light and creating the electromagnetic field in accordance with the full set of the Maxwell equations is considered. Moreover, the method of derivation is illustrated on the non-relativistic kinetic model. Independent derivation of the relativistic hydrodynamics is also demonstrated. The key role of these derivations of the hydrodynamic and kinetic equations includes the explicit operator of averaging on the physically infinitesimal volume suggested by L.S. Kuzmenkov.

期刊介绍： JPP aspires to be the intellectual home of those who think of plasma physics as a fundamental discipline. The journal focuses on publishing research on laboratory plasmas (including magnetically confined and inertial fusion plasmas), space physics and plasma astrophysics that takes advantage of the rapid ongoing progress in instrumentation and computing to advance fundamental understanding of multiscale plasma physics. The Journal welcomes submissions of analytical, numerical, observational and experimental work: both original research and tutorial- or review-style papers, as well as proposals for its Lecture Notes series.
