有些物质溶于水，它的分子（或原子）跟水分子结合生成水合分子，例如C2H5OH·H2O，NH3·H2O等等。
甲烷水合物主要存在于地下以及海底，由甲烷分子被锁在固态水晶体格中所组成。
Found underground and on the sea floor, methane hydrate consists of natural gas molecules trapped within a lattice of frozen water molecules.
这种细粉末可吸收气体，即通过化学方式与水分子结合，形成水合物。
The result is a fine powder that canslurp up gases, which chemically combine with the water molecules to form whatchemists term a hydrate.
更常见到的水合物是气体分子被圈闭在一个晶体构造内的化合物。
More generally, hydrates are compounds in which gas molecules are trapped within a crystal structure.
