摘要
参照 78国际实用盐标基本定义及其背景材料 ,利用国内现有的技术条件 ,成功地配制出了特定电导率的 KCl标准溶液。采用国际标准海水重新定值法对标准溶液的电导率准确度进行了验证。实验结果表明 ,新的盐度测量值与原标称值之差最大为 - 0 .0 0 0 8,最小为 0 .0 0 0 0 ,均在国际标准海水盐度标称值总不确定度± 0 .0 0 1范围之内 ,复现技术达到国际同等水平 ,该项研究为建立我国海水实用盐度全程量值传递奠定了基础。
According to the definition of PSS-78 and background materials, KCl standard solution having definite conductivity is prepared successfully. Then the author tests the accuracy of the standard solution by adopting the revalue method of international standard seawater. The results show that the maximum and minimum error between the measurement salinity value and nominal value are -0.0008 and 0.0000 respectively, which within the range of ±0.001, the uncertainty requirement of seawater salinity scale. This recurrence technique reaches the international level. The study gives the key support for realizing the whole-rang-value-transferring of seawater practical salinity of our country.
