摘要
本工作测定了长江沿岸三个城市上海、南京、武汉从1982年10月到1983年9月年度中每月长江水中氢氧同位素的组成。观察到长江水中氢氧同位素组成随季节而变化,水中氢氧同位素含量5月最高,10月最低。长江水中氢氧同位素组成δD、δ^(18)O间的关系为δD=7.01δ^(18)O-1.94。
The D and O content of Yangtze River water collected once a month for a one year period at Wuhan, Nanjing, Shanghai has been determined mass spectrometrically. Seasonal variation has been observed within the range δD = 30--40 and δ18O = 4--6.5 with the lowest value in October and the highest in May. The correction between 3D and δ18O is:δD=7.01 δ18O-1.94.
