| 摘 要： | 工业管道存在着紊流阻力规律不同的三个流区，但国内外的教材和手册中都只介绍以Ｎｉｋｕｒａｄｓｅ试验为基础的人工均匀粗糙管道的紊流三流区分区标准，把它推广应用于各种管材的工业管道，可能带来偏于不安全的重大误差．本文建议的分区标准，可为各种工业管道正确应用紊流分区阻力公式提供必要的和合理的依据．

| Abstract: | In industrial pipeline there are there flow zones different in resistance law to tubulent flow.However,the textbooks and handbooks published at home and abroad present only the standards for dividing three turbulent flow zones artificially averaged in rough pipeline on the basis of Nikuradse's experiments.If the standards are applied for industrial pipeline made from various materials,significant dangerous error might take place.The division standards proposed by this paper may provide necessary and riliable basis for various kinds of industrial pipeline to correctly apply the division resistance formula of turbulent flow. |

| Keywords: | industrial pipeline resistance of turbulent flow flow zone |
