摘要: 利用辐射法测量金属材料的冲击波温度时，在金属样品/透明窗口界面上卸载引起的熔化对卸载终态的影响进行了探讨，提出了利用过热卸载模型计算由于卸载熔化对终态的影响及计算公式，并给出了几种典型压力下Fe/Al2O3及Fe/LiF界面在考虑卸载熔化后的温度、熔化质量分数及体积。

Abstract: In radiometry measurements of shock temperatures for metals, release processes occurring at the metal/window interface affect substantially the final state of the tested sample, especially when release-induced melting happens. In this paper, the author describes in detail how to use a super-heating release model to evaluate the release temperature and volume of the final state when release melting occurs. Typical results for Fe/Al2O3 and Fe/LiF configurations are presented by using this model at pressures up to 270 GPa.
