基于SWAP的旱稻灌溉模式研究

针对旱稻品种HD297,以土壤-水分-大气-作物系统模拟模型(SWAP)为工具,以2003~2004年在河南柳园口灌区惠北灌溉试验站开展的旱稻不同灌溉制度试验为基础,应用不同灌溉制度下灌水水平、土壤水势、旱稻叶面积指数、干物质量及产量等试验资料,对模型模拟旱稻灌溉制度及作物生长  (本文共6页) 阅读全文>>

Feasible schemes for quantum swap gates of optical qubits via cavity QED

Feasible schemes for implementing quantum swap gates of both coherent-state qubits and photonic qubits are proposed using a Λ-type atomic ensemble trapped in a bimodal optical cavity. In both protocols,the decoherence from atomic spontaneous emission is neglig...  (本文共6页) 阅读全文>>

Optimization for vehicle scheduling in iron and steel works based on semi-trailer swap transport

In order to solve internal logistics problems of iron and steel works,such as low transportation efficiency of vehicles and high transportation cost,the production process and traditional transportation style of iron and steel works were introduced.The internal transport tasks of iron and steel works were grouped based on cluster analysis according to demand time of the transportation.An improved vehicle scheduling m...  (本文共7页) 阅读全文>>

非充分灌溉条件下农田水分转化SWAP模拟

非充分灌溉改变了农田水分转化过程,以往的研究较少讨论作物根系层以下的土壤水分转化动态及其对作物耗水的影响。该文在北京市典型农田开展了冬小麦-夏玉米非充分灌溉试验,在对SWAP模型率定与验证基础上,模拟分析了非充分灌溉农田耗水规律与水分转化过程,并应用模型得到了研究区不同降水年型的最优非充分灌溉模式。结果表...  (本文共9页) 阅读全文>>
