摘　　要：水在4℃时的密度为最大,及其反常膨胀的现象,尚未形成确切的物理解释,阻碍了人们对水的科学认知。本文基于水合作用原理,研究水分子氢键与离子和气体分子间的键合机制,以及由常态水中自然存在着的分子离子水合物所引起的溶液性质变化,首次提出水的反常膨胀源于气体分子水合物的理论假说,并通过相关实验设计得到验证。从而,基本揭示了水的反常膨胀机理——“水合作用”,为水科学的基础研究展示了新契机。It hasn't been proved by physical explanation that the density of water reaches the maximum at 4℃,and water bulges abnormally,which hinders people's scientific understanding of water.Based on hydration,this paper studies the bonding mechanism between water molecule hydrogen bond and ions and gas molecules,as well as the changes of solution properties caused by molecular ion hydrates existing naturally in normal water.For the first time,a theoretical hypothesis that the abnormal expansion of water originates from gas molecular hydrate is proposed and verified by relevant experimental design.Thus,hydration,the mechanism of abnormal expansion of water,is basically revealed,which provides a new opportunity for the basic research of water science.
