摘要：

Recent developments in shock-wave experimental techniques have allowed the 100 GPa range to be probed. The results of experiments on hydrogen have demonstrated that at 141 GPa fluid hydrogen is in a metallic state. Using analytical calculations as well as Monte Carlo simulations, the pair distribution functions in partly dissociated hydrogen are determined. The equation of state is in good agreement with experiment in this high-pressure region. Estimates for the degree of dissociation are given. Furthermore, we demonstrate the influence of dissociation oh the proton-proton pair distribution function.
