摘要
液态水有很多奇异特性.近年来,对液态水以何种微观结构形式存在的问题争议激烈.文章介绍了当前对水的微观结构的一些研究及其进展,讨论了液态水中的氢键模式与水的结构关系,进而用一个简化模型探讨了氢键的取向性与强弱性对水的异常行为的作用.
The origin of water anomalies continues to baffle scientists. Recently, studies have focused on the local structure and its impact on the anomalies of liquid water. We review the recent progress in this field, and in particular, discuss the hydrogen bonds in liquid water and its relationship with the structure. By using a simplified water model, the water anomalies due to the orientation and strong--weak duality of the hydrogen bonds are explored.
