前言近年来不少科学家对卡门过滤理论颇感兴趣,并已将它应用于许多科学领域内。美国水文学家也对卡门过滤理论十分感兴趣,并把它用于河川流量预报上,收到了良好的成效。本文拟介绍从研究汇流问题出发,引入卡门过滤公式,从而可以看到将其应用于河流流量预报上。 Preface In recent years, many scientists are quite interested in Carmen filter theory and have applied it to many fields of science. American hydrologists are also very much interested in Carmen’s theory of filtration and used it in river flow forecasting and received good results. In this paper, we introduce the Carmen filter formula from the study of confluence, so we can see that it is applied to the forecast of river flow.
