论文摘要
在部分离子化的等离子体中，离子可以处于不同电离状态，每个电荷状态都可以描述为用于多离子碰撞运输目的的不同流体。在两个电荷状态下，运输将等离子体推向平衡，这被发现是局部电荷状态平衡和代表不同电荷状态的离子流体之间的广义捏合关系的组合。这些条件结合起来导致离子的戏剧性解解。这种解料发生在时间尺度上，但与多离子跨场传输时间尺度相似，但与完全离子化等离子体中的电子离子传输时间尺度相似。发生反元是因为局部电荷状态平衡强化了离子流体成分的磁管漂移速度的差异，从而导致由于离子离子摩擦而导致跨场传输。
In partially ionized plasma, where ions can be in different ionization states, each charge state can be described as a different fluid for the purpose of multi-ion collisional transport. In the case of two charge states, transport pushes plasma toward equilibrium which is found to be a combination of local charge state equilibrium and generalized pinch relations between ion fluids representing different charge states. Combined, these conditions lead to a dramatic deconfinement of ions. This deconfinement happens on the timescale similar but not identical to the multi-ion cross-field transport timescale, as opposed to electron-ion transport timescale in fully ionized plasma. Deconfinement occurs because local charge state equilibration enforces the disparity in diamagnetic drift velocities of ion fluid components, which in turn leads to the cross-field transport due to ion-ion friction.
