摘要

摘要为高密度或低密度冰之间的转变建立了结构机制。计算了过渡过程中保留的氢键比例。估算了所考虑的冰分子填充空间的相对程度。在冰的 PvT 相图的低温区域，冰相之间存在边界，这一假设已经提出并得到部分证实。利用结构分析结果证明了构建水 PvTb 相图的新方法。氢键浓度 b 是相变的二阶参数。

Structural Mechanisms of Transitions between Ices with Different Densities—Features of Water Phase Diagrams

Structural mechanisms are developed for transitions between ices with either high or low density. Fractions of hydrogen bonds retained in the course of the transitions are calculated. Relative degrees of space filling by molecules of the considered ices are estimated. An assumption is formulated and partially substantiated that boundary exists between ice phases in the low-temperature region of the PvT phase diagram of ices. A new method for construction of PvTb diagrams of water is justified using the results of the structural analysis. The hydrogen bond concentration b serves as the second order parameter of phase transitions.
