摘要：

The electrical conductivity of warm dense tungsten plasma has been investigated successfully by a linear mixture rule considering various interactions of electrons with electrons, atoms, and ions. The plasma composition is calculated by the nonideal Saha equation. The interesting regime for tungsten plasma spans from weakly coupled and nondegenerate regime to strongly coupled and partial degenerate state. The electrical conductivity calculated is in reasonable agreement with the exploding wire experiments and other theoretical models. The present result demonstrates that the theoretical model is valid for the electrical conductivity of tungsten plasma in the warm dense matter regime. (C) 2013 Elsevier B.V. All rights reserved.
