海洋台站不确定性数据表示方法的研究
ON EXPRESSION OF UNCERTAIN DATA FOR MARINE STATIONS
摘要
Abstract
Aiming at current status quo of the uncertainty of marine station data, in this paper we analyse two typical expressions of uncertain data, ihe Trio and the MayBMS. Based on that and according to the characteristics of uncertain data of marine stations, we introduce an expression method fitting the uncertain data of the marine stations. Experiment shows that this method can eliminate the redundant information that existing expression means may has and reduce the total number of relation tables formed effectively. It lays a foundation for the study of efficient query method for uncertain data of the marine stations.关键词
