| 摘 要： | 在气炮加载试验中利用弹载光源原位测试技术，观测了夹于石英玻璃之间的水在动态压缩过程中的透光特性. 通过其光透射特性研究了水的冲击相变. 实验结果发现液态水在动态冲击压缩过程中, 其压力低于2 GPa 就出现透明性变差的现象，而且水的透明性下降与石英玻璃的存在有关，是一种石英诱导水的结晶相变现象.

| Abstract: | Optical transmission characteristics of water between quartz glass under shock compression are in situ observed by using the technique of missile-borne light source. Through these transmission properties, the phase transition of liquid water is studied. The experimental results show that liquid water exhibits transparency decline phenomenon when the pressure is lower than 2 GPa under shock compression process, and the transparency variation is related to the existence of quartz glass. So, the transparency decline is attributed to a quartz-induced freezing phenomenon of water. |
