Abstract

Abstract:

On the basis of the non-equilibrium statistical theory, the transport equations of various impurity ions, deuterium ions and electrons, namely the special multi-component plasma, were derived from Fokker-Planck kinetic equation. The transport dynamics of impurity ions with Zth-level charges forming in the various ionization levels and the contribution of explicit collisions between different particles were systematically analyzed. In addition, the obtained transport equations of various impurity ions are more compact and elegant.

摘要：

以非平衡态统计理论为基础，从福克尔-普朗克动理学方程出发推导出了各种杂质离子、氘离子和电子的输运动力学方程，即特殊的多组分等离子体输运方程。各级电离过程中形成的带不同电荷杂质离子的输运动力学过程以及不同粒子间碰撞相互作用的贡献在文中进行了系统的分析。此外，在重新推导并优化的基本方程组基础上，得到了各种杂质离子的输运动力学方程。
