摘要: 用光辐射法、以有机玻璃作窗口测量了143～182 GPa下H62黄铜的追赶稀疏波速度。给出了在对称碰撞下，用透明材料作窗口时，实验确定追赶稀疏波速度的公式。实验结果表明，H62黄铜的冲击熔化点在143～162 GPa之间。Abstract: Overtaking rarefaction velocities in shock-loaded H62-brass were measured by using radiometry in the pressure range from 143~182 GPa, and the PMMA were used as the window material. Formulae for determing the overtaking rarefaction velocity are given in case of a symmetrical impaction. The experimenal results showed that the shock melting in H62-brass are occured in the region between 143 and 162 GPa.
