【 摘 要 】

Temperature is notably the most difficult quantity to measure in shock compression experiments; however, it is critical for accurately constraining theoretical or tabular equations of state. Until now, the temperature achieved during the shock loading of porous materials could only be calculated. The technique presented in this report measures, for the first time, the shocked temperature of porous systems.
