摘要
本文介绍了海面大气折光系数的意义、用途和国外某些国家在航海上采用该数值的情况;作者根据1987年在中国南海、北海(黄海)和东海海域对海面大气折光系数进行定点规测所获得的2074组有效数据,初步求出了中国海区海面大气折光系数平均值的情况;同时通过微机处理进行多次线性回归,得出了求海面大气折光系数瞬时值的经验公式;对进一步开展研究这—课题的重要性、必要性和可行性提出了一些意见。
This article gives an introduction of the significance and func-tion of the atmospheric refraction index at sea and the applica-tion of the index in the navigation of some countries. Accordingto 2 074 groups of effective data gained through the fixedpointobservation of the atmospheric refraction index at the South,East and North (Yellow) Chilla Sea in 1987, the author obtainedthe original average value of atmospheric refraction index at theChinese sea area. He proposed an empirical formula for thecalculation of the instantaneous coefficiant of the atmosphericrefraction index at sea by making linear regression at microcom-puter. Finnaly, he gives some comments on the importance,neccessity and feasibility of carrying out further researches onthe project.
