膜孔肥液单向交汇入渗特性及数学模型研究OA北大核心CSCDCSTPCD
Mathematical models for single-line interference infiltration of fertilizer solution in film hole
通过室内入渗试验,分析了膜孔肥液单向交汇的入渗特性.在此基础上,根据已知试验资料,提出了Kostiakov模型、分段函数模型、减渗量模型和增渗率模型等4个膜孔肥液单向交汇入渗模型.Kostiakov模型建立的条件是膜孔肥液单向交汇入渗参数均为已知；分段函数模型建立的条件是膜孔肥液自由入渗和单向交汇入渗参数均为已知；减渗量模型建立的条件是膜孔肥液单向交汇入渗相对于膜孔肥液自由入渗的减渗置参数和膜孔肥液自由入渗参数已知；增渗率模型建立的条件是膜孔肥液…查看全部>>
Based on lab. experiment, characteristics of single-line interference irrigation of fertilizer solution in film hole were analyzed. Four mathematical models were presented based on different measured data, such as Kostiakov model , piecewise function model, reduction volume model and increasing infiltration ratio model for film hole fertilizer solution single-line interference irrigation. Kostiakov model is based on the infiltration parameters of film hole s…查看全部>>
