摘要：

The Monte Carlo simulation method of Panagiotopoulos has been used to study the fluid-fluid phase behavior of the helium-hydrogen system up to high pressures and temperatures. The influence of the attractive part of the potential has been investigated by carrying out the simulations also for the purely repulsive system. It is shown that fluid-fluid equilibrium in the helium-hydrogen system persists up to at least 700 kbar and 2500 K. The attraction causes a shift of the critical line to higher temperatures. Implications of these results for models of the Jovian planets are discussed.
