摘要:
通过对膜孔灌可行性研究,阐明了膜孔灌节水增产的机理.在探讨膜孔入渗规律的基础上,提出了膜孔灌可变灌水强度新概念及数学表达式.并根据膜孔灌水流现象,把膜孔灌过程划分为四个阶段,进而分析了各阶段的水流状态.在不定流动方程的基础上,提出了用差分法求解膜孔灌方程的建议.为方便应用,作者又提出了膜孔灌简易方程及解题步骤.
Abstract:
Through feasible research on film hole irrigation,this paper expounds production-increased and water-conserved principle of film hole irrigation.Based on the law of studying filmhole permeating,the authors put forward the new concept of changeable irrigation intensity and the mathematic expressive formula for film hole irrigation.Repending on the phenomena of film hole irrigation,the authors divide irrigation procedure into four stages,and fully analyse water’s state of each stage.On the basis of unconstant flowing formula,the authors pose the suggestion of solving film hole irrigation formula with the method of finite difference.In order to apply more convenient,the authors pose simple formula and solving question step for film hole irrigation.
