应用CTD装置测量海水电导率、温度和压力,然后进行自动计算得到盐度值,需要知道这四个变量间的准确的数学关系,即需要确立一组完整的计算方程式。这方面的工作,包括这些方程式的推出、建立、运算、修正、验证和相互比较,已有若干学者专家分别进行多年,成果陆续发表,迄今可认为已告完成。其中海水盐度、电导率和温度的相互关系,
Using CTD devices to measure seawater conductivity, temperature, and pressure and then automatically calculating salinity values requires an understanding of the exact mathematical relationship between the four variables, ie, the need to establish a complete set of equations for calculation. A number of scholars and experts have been working for many years and achievements have been published in these fields, including the introduction, establishment, computation, revision, verification and comparison of these equations. So far, they have been concluded that they have been completed. Among them, the relationship between seawater salinity, conductivity and temperature,
