海水氯度值是海水的一个重要参数。自从本世纪初,Knudsen建立了氯度的定义及其测定方法以来,在世界大洋及大陆临近海域上取得了大量的调查资料。过去曾研究了许多氯度与盐度、密度及其他一些海水物理化学性质的相互关系,监建立了许多经验公式。例如,海水盐度的确定,过去基本上都是根据氯度的测定,再按盐度公式计算得出的;密度亦同。虽 Chloride value of seawater is an important parameter of seawater. Since the beginning of this century, Knudsen has established a large amount of survey data on the oceanic and continent seas since the establishment of the definition of chlorinity and its determination method. In the past, many interdependences between chlorinity and salinity, density and other physical and chemical properties of seawater have been studied. Many empirical formulas have been established. For example, the determination of seawater salinity, the past basically based on the determination of chlorinity, and then calculated by the salinity formula; the same density. although
