摘要：

In this paper, Green's function technique is applied to calculate the EOS for weakly coupled plasmas. Especially, the Montroll Ward approximation is used to cover the density-temperature region where correlations as well as Fermi statistics have to be taken into account. First, low and high density expansions for the thermodynamic functions of two-component plasmas are presented, Then, the EOS in Montroll-Ward approximation is calculated by numerical evaluation. Results for hydrogen and for an electron-positron plasma are given, We compare our numerical results with recent data from quantum simulations and use our EOS theory to investigate correlation and quantum effects of the mean kinetic energy.
