By use of two-stage light-gas gun, the thermodynamic states of hydrogen-helium mixture at lOOGPa and 3000-5000K is firstly reached and actually measured in laboratory, and some EOS data of them is respectively obtained.

• 利用二级轻气炮加载手段,在实验室首次获得了氢氦混合物体系在接近100GPa和3000-5000K区域的高温高压状态,并分别获得了一组氢、氦及其混合物状态方程数据。
