Abstract—

Factors affecting the calculation of the electrical conductivity of hot dense nonideal plasma systems are revisited and scrutinized. Essential features relevant to truncation of the internal partition function, Coulomb strong coupling, electronic excited states, in addition to high ionization boundary and Coulomb logarithm, are thoroughly investigated and assessed. Particular interest has been given to the study of the frequently occurring problem of producing intersecting conductivity isotherms at high densities. An improved model for the prediction of the electrical conductivity of hot dense matter is developed and used to calculate the electrical conductivity of partially ionized and partially degenerate matter at high energy density. Compared to results from competitive models in the literature, predictions from the present model have shown better physical behavior in avoiding the problem of producing intersecting isotherms at high densities.

热致非理想等离子体电导率的计算

摘要-

考察并研究了影响热致密非理想等离子体系统电导率计算的因素。彻底研究和评估了与内部分配函数的截断，库仑强耦合，电子激发态以及高电离边界和库仑对数有关的基本特征。对于在高密度下产生相交的电导率等温线的经常发生的问题的研究已经引起了特别的兴趣。建立了改进的热致密物质电导率预测模型，并将其用于计算高能量密度下部分电离和部分简并物质的电导率。与文献中竞争模型得出的结果相比，
