Scientists have isolated the two different forms of water molecule for the first time. 近日，科学家们首次成功分离出两种不同形式的水分子。 Water molecules were known to exist as two distinct "isomers", or types, based on their slightly different properties at the atomic level. 基于原子水平上略微不同的性质，已知的水分子可以以两种不同的“异构体”类型存在。 By separating out the two isomers, researchers were able to show that they behave differently in the way that they undergo chemical reactions. 通过分离出两种异构体，研究人员能够证明它们在进行化学反应时可以表现出不同的行为。 |
