月球表面每吨土壤含水量达一升。不过,说起“月球上的水”,并不是说湖、海或水洼。Carle Pieters, of Brown University, who led the Chandrayaan-1 observation team, said: “When we say ‘water on the moon’, we are not talking about lakes, oceans or even puddles. 月球上的水特指月球表层几毫米内与岩石分子和粉尘相互作用的水分子和羟基。(From The Times, September 24, 2009: Moon 'has a litre of water for every tonne of soil')
puddle: (noun) a small amount of water or other liquid, especially rain, that has collected in one place on the ground. 水洼;小水坑;(尤指)雨水坑。
