"Mopping up" excess hydrogen ions - Neutralizing substances in the blood, such as bicarbonate and hemoglobin, mop up excess hydrogen ions and prevent pH from becoming too acidic.
“扫除”额外的氢离子—血液里的中和物质，如重碳酸盐和血红蛋白，扫除了多余的氢离子防止PH值变得太酸。
Ocean acidification has further chemical implications: more hydrogen ions mean more bicarbonate ions, and fewer carbonate ions.
海洋酸化还会进一步引起连锁化学反应：更多的氢离子意味着碳酸氢根离子多了，而碳酸根离子少了。
