Studies On Equation Of State Of The Mixtures Of Dense Hydrogen And Helium In High-Temperature And -Density

Hydrogen and helium are the most abundant elements in the universe, and also the main components in some planets, such as Jupiter, Saturn. The properties of hydrogen(H₂), helium(He) and their mixture(H₂+He) in a specifically range of temperature and density are crucial for the evolution of starts and the characteristic of the Jovian planets. Meanwhile, the equations of state(EOS) of H₂, He and H₂+He in high-temperature and -density have great scientific significance and application values for inertial confinement fusion(ICF) induced by laser, and for exploitation and utilization of new energy resource. Therefore both experimental and theoretical physicists pay much attention to study the properties of H₂, and He in ultra conditions. Lots of investigations on the EOS of H₂ and He have done, but their mixture attracted little attention and no experiments on H₂+He have been reported at abroad. Some studies on H₂+He have done at interiorly, but the initial densities of H₂+He are not very high with normal temperature. As well as knows, the gaseous density will be higher with higher pressure and lower temperature. So some researches on H₂+He with the initial of high pressure and low temperature are necessary to get high shock pressure and temperature.This article main do some experimental and theoretic researches on high-temperature and -density of H₂, He and H₂+HC In the shock compression...
