carbonic

Should the carbon dioxide mix with water underground and form carbonic acid, they say, it could leach poisonous materials from rock deep underground that could then seep out.

他们说，一旦二氧化碳与地下水融合极易形成碳酸，而这会把地下岩石中的有毒物质分解出来，从而污染我们的水资源。

A new mathematical analysis solves a longstanding cave-formation puzzle: how a trickle of water laced with carbonic acid manages to quickly dissolve rock to create massive conduits.

一个全新的数学分析方法解决了一个长期存在的洞穴形成难题：含有碳酸的一股细流如何快速溶解石头从而产生了大量的通道。
