摘要:
通过海洋调查所得到的海水温度、盐度和深度值进行海水比容偏差及海水比容值计算时,由于要求这样计算出来的值有±1×10-5的精确度,以适应动力计算的需要,因而便要求温度、氯度和深度的调查值各有一定的精确度。对于深海来说,这个问题比较明确,可是对于浅海在100米的范围来说,对这些调查值的精确度将如何要求呢?下面就在作者1955年论文的基础上,进一步研究这个问题。
Abstract:
This paper investigates the accuracy of the measurements of temperature, chlorinity and depth in shallow seas less than 100 meters deep, which are necessary to meet the need of the required accuracies ±1×10-5 of the calculated values of the anomaly of specific volume of sea water and of specific volume itselfy.The ranges of measurements of temperature, chlorinity and depth are -2℃-30℃, 5‰-20‰ and 0m-100m respectively. In general, the accuracy of temperature measurement necessary to meet the required accuracy ±1×10-5 of the calculated value of anomly of specific volume, is leaver in the low temperature and low chlorinity case than in the high temperatre and high chlorinity case;however, the necessary accuracy of the measurments of chlorinity is higher in the low temperature and low chlorinity case than in the high temperature and high chlorinity case. Generally speaking the accuraces necessary to meet the required accuracy ±1×10-5 of the calculated value of specific volume of both the temperature and chlorinity increases as the accuracy of measurements of depth decreases either in lower temperature and lower chlorinity case or in higher temperature and higher chlorinity case.
