长期以来,全流观点曾在海流理论中占居统治地位,人们运用全流观点初步阐明了海水运动的某些基本规律。这种理论的实质在于通过流速的深度积分将作为三维问题的海水运动转成平面问题加以研究,从而使问题的数学处理大为简化。无疑,这样就排除了研究流场空间结构的可能性。此外,为了验证从全流理论所获得的结论,作者们在选择全流速度无辐散层时带有很大的偶然性与任意性,通常将表层流速即当作全流速度。为了避 For a long time, the view of the whole flow had dominated the current theory of the sea, and people used the point of view of the whole flow to preliminarily clarify certain basic rules of the sea water movement. The essence of this theory lies in the fact that the problem of mathematical processing is greatly simplified by studying the seawater movement as a three-dimensional problem into a plane problem through the depth integral of flow velocity. No doubt, this ruled out the possibility of studying the spatial structure of the flow field. In addition, in order to validate the conclusions obtained from the theory of the whole flow, the authors have a great chance and arbitrariness in the choice of velocity-free layer at full flow velocity, and the superficial velocity is usually regarded as the full flow velocity. To avoid it
