我们海洋调查队曾多次承担过新仪器在海上的比测工作,也曾多次派人参加过新仪器的标定会议,作为使用单位的代表而提出的比测报告和观测数据对新仪器的结论有效大的影响。现对当前新研制的海洋仪器的比测工作提一点个人看法,供有关方面参考。一、比测时,比测所用仪器的精度应该高于或至少应该与研制仪器具有同等精度。山东海洋学院研制的实验室用电导盐度计,曾让我们用硝酸银滴定法所测盐度值与之比测。大家都知道电导盐度计的精度较高,可达0.003‰,而滴定法除了此方法本身存在一定的误差外,而其分析误差就达0.02‰,以后者为“标准”去比测前者显然是不合适的。
Our marine investigation team has repeatedly assumed the work of measuring new instruments at sea and has repeatedly sent people to participate in calibration meetings of new instruments. As a representative of the employing units, we have provided comparative reports and observation data on the new instruments Conclusion effective and big impact. At present, the current newly developed oceanographic instruments to measure the work of a little personal view for reference. First, the ratio test, the accuracy of the instrument than the test should be higher than or at least should be developed with the same precision instruments. Shandong Institute of Ocean Laboratory conductivity conductivity salinity meter, let us use the silver nitrate titration measured value of salinity with the ratio. We all know that the conductivity of the salinity of high accuracy, up to 0.003 ‰, and titration method in addition to this method itself there is a certain error, while the analysis error of up to 0.02 ‰, the latter for the “standard” to test The former is obviously not suitable.
