molecular water

我国科研团队在嫦娥五号月球样品中，发现了一种富含水分子的未知矿物晶体。这是科学家首次在月壤中发现分子水。
A team of Chinese scientists has identified in a lunar sample retrieved by Chang'e-5 a kind of mineral enriched with water in its molecular structure. The researchers said this discovery signifies the first direct detection of molecular water within the lunar regolith.
