  Two-temperature, two-mass quasi-equilibrium plasmas may occur in electron-ion
plasmas,nuclear-matter, as well as in electron-hole condensed-matter systems.
Dense two-temperature hydrogen plasmas straddle the difficult partially -
degenerate regime of electron densities and temperatures which are important in
astrophysics, in inertial-confinement fusion research, and other areas of warm
dense matter physics. Results from Kohn-Sham calculations and QMC are used to
benchmark the procedures used in classical molecular-dynamics simulations, HNC
and CHNC methods to derive electron-electron and electron-proton pair -
distribution functions. Then, nonequilibrium molecular dynamics for two
-temperature, two-mass plasmas are used to obtain the pair distribution. Using
these results, the correct HNC and CHNC procedures for the evaluation of
pair-distribution functions in two-temperature two-mass two-component charged
fluids are established. Results for a mass ratio of 1:5, typical of
electron-hole fluids, as well as for compressed hydrogen are presented. PACS
