海水组成守恒性 亦即海水主要成分恒比关系。1884年英国人狄特玛(Dittmar)证实:虽然大洋海水的盐度是可变的,但海水主要成分之间的比值却几乎保持恒定。由此,只要知道海水的一种主要成分,则可计算其他主要成分。 主要元素和微量元素 海水中主要元素指Na~+、K~+、Mg~(2+)、Ca~(2+)、Sr~(2+)、B、CI~-、SO_4~(2+)、HCO_3~-、Br~-和F~-(11)个离子而言,占海水中总盐量的99.9％以上,其浓度均在1ppm以上。其在大洋中均遵从海水组成守恒性,所以也称其为“保守成分”。海水中微量元素一般指除主
The conservation of seawater is also the main component of seawater constant ratio. Dittmar, an Englishman in 1884, confirmed that although the salinity of ocean waters is variable, the ratio between the major components of seawater remains almost constant. Thus, as long as you know one of the main components of seawater, you can calculate the other major components. The major elements and trace elements in seawater are Na +, K +, Mg2 +, Ca2 +, Sr2 +, B, CI ~ -, SO4 ~ (2+ ), HCO_3 ~ -, Br ~ - and F ~ - (11) ions, accounting for more than 99.9% of the total salt content in seawater, and their concentrations are all above 1ppm. It complies with the conservation of seawater composition in the ocean, so it is also called a “conservative component.” Sea water trace elements generally refers to the main addition
