论文摘要
提出了一个新模型，用于具有无调参数的离子物种混合物的致密等离子体的电导率。该模型将该物种的温度，质量密度和相对丰度作为输入。它考虑了部分电离，离子结构和核心价正交性，并使用横截面的量子机械计算。与现有的高保真度相比，但计算昂贵的方法显示出良好的一致性。新模型在计算上是有效的，可以达到高温。还提出了一个新的混合规则，可为高温血浆混合物提供合理准确的电导率。
A new model for the electrical conductivity of dense plasmas with a mixture of ion species, containing no adjustable parameters, is presented. The model takes the temperature, mass density and relative abundances of the species as input. It takes into account partial ionization, ionic structure, and core-valence orthogonality, and uses quantum mechanical calculations of cross sections. Comparison to an existing high fidelity but computationally expensive method reveals good agreement. The new model is computationally efficient and can reach high temperatures. A new mixing rule is also presented that gives reasonably accurate conductivities for high temperature plasma mixtures.
