It changes soil, preserves food, inspires polar explorers and gives hope to those in search of resurrection now that bodies can be preserved in liquid nitrogen.

它可以改变土壤状况，保存食物，激励极地探险，给予那些保存在液氮的人们再次复苏的希望。

Both beer and shampoo have polar molecules that accumulate at a liquid-gas interface, but the mechanisms that prevent bubble collapse in soap foams or pilsner heads are fundamentally different.

啤酒和洗发水都有极性分子，它们可以在气液分解面上积累，但是阻止气泡破掉的机制，对于肥皂沫和啤酒来说，有着根本上的区别。

If the source of Enceladus' south polar geysers, discovered by Cassini in 2005, is indeed liquid water, then the geysers will transport the dissolved sodium into space.

如果2005年我们通过卡西尼探测器在土卫二南极地区发现的冰晶喷泉，实际上是土卫二内部的液体水从土卫二逃逸的出口。那么这些冰晶喷泉也许就是现在被发现的钠元素的起源地。
