摘要
本文研究了微灌系统中支、毛管允许压力差的优化分配问题。西北水利科学研究所杨建康同志曾提出了平地情况下的优化分配比公式,本文则进一步推导出了均匀坡度情况下的优化分配比公式。
This paper deals with the optimal allotmenl of the pressure deviation of manifold and lateral in Micro-irrigation systems. Following the formula of optimal ratio on lovel land developed by Yang Jiankang (North-west Water Conservence Research Institute), the author of this paper develops furcther a formula of optimal ratio on even slops.
