石英玻璃界面处水的异常冲击相变现象

The Abnormal Phase Transition of Water at Quartz/Water Interfaces under Shock Compression Process

在轻气炮上利用弹载光源原位测试技术,适时观测了夹于石英间的液态水在冲击压缩过程中的透光性,通过光透射率特征对水的冲击结构相变进行了分析研究。实验结果发现液态水在多次冲击压缩过程中,其热力学状态虽然未达到相变发生的条件却出现导致透光性变差的异常相变现象。经分析认为该异常相变是一种石英玻璃诱导水的结晶相变现象。

In this paper,a missile borne light source in-situ test technique was used in gas gun.It researched the water＇s shock-induced phase transition by observing the water sandwiched between the quartz-glass,whose translucency in the process of shock compression.The experimental results found that liquid water in multiple shock compression process,its thermodynamic state is still in the liquid region and the abnormal phenomenon of phase transformation is turned up.The analysis considers that the abnormal phase transition is a kind of quartz glass induced the crystallization of water phase transition.
