摘      要：Quantum molecular dynamic simulations have been employed to study the equation of state(EOS)of fluid helium under shock *** principal Hugoniot is determined from EOS,where corrections from atomic ionization are added onto the calculated *** simulation results indicate that principal Hugoniot shows good agreementwith gas gun and laser driven experiments,andmaximum compression ratio of 5.16 is reached at 106 GPa.
