论文摘要
分析了非理想的铜血浆在真空中分析真空的真空，真空弧中爆炸性电子发射的条件。使用电子库仑偶联引起的电离能校正，使用一个状态方程（EOS）解决了欧拉方程（EOS）方程。我们获得的是，当等离子体特性和组成发生巨大变化时，EOS对血浆膨胀的影响不大。基于我们的仿真结果，真空弧等离子体诊断中经常使用的“冷冻”状态理论的有效性值得怀疑。
The expansion of non-ideal copper plasma into vacuum is analyzed for the conditions typical to explosive electron emission in vacuum arcs. The gas-dynamic model solves the Euler equations with an equation of state (EoS) for weakly non-ideal plasma taking into account the ionization energy correction due to electron-ion Coulomb coupling. We have obtained that the EoS has insignificant influence on the plasma expansion, when the plasma properties and composition change drastically. Based on our simulation results, the validity of the 'frozen' state theory often used in the vacuum arcs plasma diagnostics is questionable.
