论文摘要
在各种不同的系统中，高Z离子物种在高血浆密度的区域中表现出明显的积累趋势。以前已经提出，当系统必须遵守双相情感条件时，可以在最大透镜状态下，可以在热力学上解释这种行为的明显普遍性。但是，先前的处理不允许温度梯度的可能性。在这里，使用非平衡（ONSAGER）热力学的工具来表明，在温度梯度的情况下，Ambiallity继续在产生这种行为方面发挥关键作用，并恢复在这些情况下出现的众所周知的温度筛查效果。
In a variety of different systems, high-Z ion species show a marked tendency to accumulate in regions of high plasma density. It has previously been suggested that the apparent universality of this behavior could be explained thermodynamically, in terms of the maximum-entropy state attainable when the system must obey an ambipolarity condition. However, the previous treatment did not allow for the possibility of temperature gradients. Here, tools from non-equilibrium (Onsager) thermodynamics are used to show that ambipolarity continues to play a key role in producing this behavior in the presence of temperature gradients, and to recover well-known temperature screening effects that appear in these cases.
