我们用热力学格林函数技术计算了稠密氢等离子体和量子电子气的热力学性质。我们的微扰方法适合于在弱耦合区域给出可靠的结果。特别地，对于非简并情况和密集的高简并量子区域，完全包含了e(4)级交换项的贡献。我们将状态方程的结果与不同数值模拟得到的数据进行了比较。
We calculate thermodynamic properties for a dense hydrogen plasma and a quantum electron gas using thermodynamic Green's function techniques. Our perturbation approach is appropriate to give reliable results in the weak coupling regime. In particular, the contribution of the exchange term of the order e(4) is fully included for the nondegenerate case as well as for the dense highly degenerate quantum region. We compare our results for the equation of state with data obtained by different numerical simulations.
