论文摘要
由于电子和离子之间存在巨大的质量差异,因此电子离子等离子体中的热扩散表现出比在典型气体混合物中发现的简单热扩散更复杂的行为。特别是,热量在两个不同但耦合的通道中扩散。常规的单流体模型忽略了所得的复杂性,并且通常不准确地解释热脉冲实验的结果。但是,通过识别电子温度演变对离子扩散率的敏感性,不仅可以正确解释先前的实验,而且可以同时测量离子和电子热通道。
Because of the large mass differences between electrons and ions, the heat diffusion in electron-ion plasmas exhibits more complex behavior than simple heat diffusion found in typical gas mixtures. In particular, heat is diffused in two distinct, but coupled, channels. Conventional single fluid models neglect the resulting complexity, and can often inaccurately interpret the results of heat pulse experiments. However, by recognizing the sensitivity of the electron temperature evolution to the ion diffusivity, not only can previous experiments be interpreted correctly, but informative simultaneous measurements can be made of both ion and electron heat channels.
