冲击压缩条件下熔石英对水的液-固相变的诱导

Liquid-solid of water induced by fused quartz under shock compression

在气炮加载实验中,利用在线的光透射测量技术研究了水在多次冲击压缩过程中的液-固相变.实验研究结果表明当水夹于熔石英之间时,熔石英对水的液-固相变具有明显的诱导作用.经分析诱导原因是熔石英中的二氧化硅与水之间存在相互作用,使得熔石英表面的水分子具备了成核相变的条件.

The liquid to solid phase transition of water is studied using time-resolved optical transmission measurements in multiple shock wave compressions. The experimental results show that the liquid-solid phase transition of water can be presumed to be promoted by the fused quartz when the water is confined between fused quartz. The analysis considers the presence of interaction between interaction between water and silicon dioxide in fused quartz, lead to near the interface water rrtolecules have conditions phase transition.
