用基于化学图像的暖态稠密物质物态方程模型计算了氢、氘、氦的主Hugoniots，氘、氦等熵压缩的再震态和三震混响的热力学计算。考虑了带电粒子的库仑相互作用、重粒子的短程排斥和吸引以及自由电子的部分简并。计算结果与气炮、炸药、磁发射飞片、激光实验以及第一性原理模拟结果进行了比较。关键词：冲击波，高压
Model for equation of state of warm dense matter based on chemical picture was used for calculation of principal Hugoniots of hydrogen, deuterium and helium, calculation of thermodynamics for reshock states and third-shock reverberation of deuterium and isentropically compressed helium. Coulomb interaction of charged particles, short-range repulsion and attraction of heavy particles and partial degeneracy of free electrons was taken into account. The calculation results were compared with gas-gun, explosive, magnetically launched flyer-plate, laser experiments and with the results of the first principle modeling. Keywords: Shock waves, High pressures
