| 摘 要： | 利用液氮冷靶系统制取液氩样品，以二级氢气炮作为加载工具，驱动飞片对液氩样品进行平面冲击压缩，实验测量了33 GPa冲击压力以下液氩的冲击温度。飞片速度由磁测速系统测量，冲击波速度和冲击温度用光纤耦合高温计系统测量，粒子速度采用阻抗匹配法计算得到。实验测得当冲击压力为33 GPa时，液氩的冲击温度超过10 000 K；而当冲击压力超过30 GPa时，冲击温度的上升趋势与理论计算相比明显变缓，该压力点正好与以前测得的冲击波速度-粒子速度曲线的拐点一致。 |

| Abstract: | Shock temperature of liquid argon has been measured under the shock pressure up to 33 GPa by employing the two-stage light gas gun. Impactor velocities were measured with electrical-magnetic induction system. Shock velocities and shock temperature of liquid argon were measured by using optical-fiber pyrometer. Mass velocities were obtained by mean of shock impendence matching method. The experimental data shows that shock temperature reach 10 000 K at 33 GPa shock pressure. Over 30 GPa shock pressure, shock temperature is lower compared with theoretical data. The experimental data also shows that the slope of shock temperature-shock volume curve begins to decrease over 30 GPa, which is the same shock pressure as the previously published shock Hugoniot curve. |
