浅论裘布衣模型的缺陷及改进方法

本文从原始的裘布衣假设模型进行分析,得出其存在的缺陷,主要包括忽略垂直分量引起的误差;处理稳定流问题时我们应该取消影响半径的概念,淡化稳定流与非稳定流之分,以非稳定流理论(包括稳定阶段)统一思想和工作方法;以及井损、水跃值引起的误差等问题的论述,以及一些改进方法。

Brief analysis of flaws of the model of J.Dupuit and improvement methods

This paper carries on the analysis from the primitive hypothesis model of J.Dupuit, obtains its flaws, mainly includes the inaccuracy which neglecting the vertical component causes; When processing steady flow question we should cancel the concept of the influence radius, desalinates steady flow and the unsteady flow, (including stable stage) unifies the thought and the method of work by the unsteady flow theory; and the elaboration of the well loss question and water-leap value question, as well as some improvement methods.
