越来越酸的海洋近年来,科学家注意到全球的海洋越来越酸了。众所周知,pH值是衡量溶液酸碱度的一个标准,pH值为7的溶液是中性的,高于7为碱性,低于7为酸性。pH值降低就意味着酸度增加。
Increasingly acidic sea In recent years, scientists have noticed that the ocean around the world is getting sour. It is well-known that pH is a measure of the pH of a solution. A solution of pH 7 is neutral, above 7 is alkaline, and below 7 is acidic. A decrease in pH means an increase in acidity.
