超临界H2O状态方程、密度、声速及液固线

理论计算认为在高温高压下存在超离子态的冰。但是目前仍然没有实验结果能够准确的证实它的存在范围。以往有关冰的高温高压XRD和布里渊数据点过于稀疏，在它可能出现的区域不能很好的观察到异常。本数据集主要包括超临界流体XRD数据和布里渊波速数据。XRD数据包含了超临界流体的晶体结构信息，布里渊数据包含了在高温高压下超离子态冰的波数数据以及弹性性质。

Theoretical calculations have predicted the existence of superionic ice under high temperature and high pressure. However, no experimental results have thus far accurately confirmed the exact range of its occurrence. Previously reported XRD and Brillouin data for ice under high-temperature and high-pressure conditions are too sparse to effectively detect anomalies in the regions where superionic ice could exist. This dataset primarily consists of XRD data for supercritical fluids and Brillouin wave velocity data. The XRD data contains crystal structure information of supercritical fluids, while the Brillouin data includes wave number data and elastic properties of superionic ice under high-temperature and high-pressure conditions.
