3) water allocation
水量配置
4) indirect collocation method
间接配置法
5) space allocation of water resources
水资源空间配置
1.
By assuming the weight water-shortage rate of each water-demanding unit to be equal and minimizing the optimization goal,the water diversion models of the weight water-shortage rate with or without consideration of the backwater are established,making the space allocation of water resources more reasonable.
为了在水资源空间配置过程中体现用户公平和避免"平均主义",结合权重和缺水率2项因子提出需水单元权重缺水率的概念,并以各需水单元权重缺水率相等且最小为优化目标分别建立了不考虑回水时的权重缺水率分水模型和考虑回水时的权重缺水率分水模型,使得水资源空间配置更合理。
6) indirect moment matching
间接矩量匹配

饱和持水量测定
measurement of saturation moisture capacity
匕aohe ehishuiliang eeding饱和持水t测定(measurement of satu-ration moisture eaPaeity)土壤农业水文特性测定项目之一,是测定土壤孔隙完全充满水时的l几壤湿度。饱和持水t所占容积等于土壤总孔隙度,可用来鉴定土壤水分饱和程度和总孔隙度。 测定方法是浸水饱和法。即在欲测地段上,用容重环刀取原状土,取土方法与测定卜壤容重时取_L相同(见土壤容l测定)。把装有未遭破坏土样的环刀称重后,使其有孔底一端(内垫滤纸)朝下,放在盛水的平底磁盘中或充满水的砂层上,使盘内水面与环刀上缘保持一样高,切勿使水面淹没环刀,以免影响空气自土壤孔隙排出,使水不能充满孔隙。经过一定时间后(砂土4一8小时,粘土8一12小时)迅速取出,用盒盖托住称重。然后再放入盘中,继续使水充满孔隙,直至前后两次重量无显著差异为止。为了计算环刀中土体的干土重,必须在同一土层上,另取土样,用称重烘干法测其湿度。用下式计算饱和持水量(占干土重的百分数): 环刀中上样吸水饱和*、、、。_后的含水量吧刊’寸小里一环万币王释的不干甭入川U.式中上样干土重(克)=环刀中的湿土重(克)xl()0100十上样湿度的百分数 此外,通过下式也可计算饱和持水量(占干土重的百分数):饱和持水量二总孔隙度 容重火10()%式中总孔隙度二1一宣重比重(林家栋)
