摘要

金属等离子体的组分为计算热力学、光学和辐射输运特性研究提供了基本的输入参数.为获得此参数,本文用部分电离等离子体模型,在考虑金属发生三次电离,以及电子与中性粒子的极化作用、离子与离子之间、电子与离子之间、电子与电子之间库仑相互作用下,计算得到了等离子体组分,进而用线性响应理论计算了金属钛和银的电导率.并与已有的实验数据进行了比较,验证了模型的可靠性.在此基础上进一步预测了密度在0.001—2.0 g/cm3、温度在1.5×104—2.5×104

Abstract

The composition of metal plasmas provides the fundamental parameters for the thermodynamic, optical, and transport properties research. In this paper, the composition of the plasmas, considering the threefold ionization of metal, the polarization between neutral particles and electron, and the Coulomb interactions among the charge particles, (including ion-ion, electron-ion, and electron-electron interactions), is calculated by partially ionized plasma model. Furthermore, the electrical conductivities of titanium and silver are calculated by using linear response theory. The reliability of the model is verified by comparing with available experimental data. Furthermore, the thermal conductivities and thermopower of titanium and silver in the range of 0.001—2.0 g/cm3, 1.5×104—2.5×104 K are predicted, which provides the reference for the experiment of transport properties of metal plasmas.
